Keil & Delitzsch

On Psalms 139:1-7

The Aramaic forms in this strophe are the ἅπαξ λεγομ רע (ground-form רעי) in Psa 139:2 and Psa 139:17, endeavour, desire, thinking, like רעוּת and רעיון in the post-exilic books, from רעה (רעא), cupere, cogitare; and the ἅπ. λεγ. רבע in Psa 139:3, equivalent to רבץ, a lying down, if רבעי be not rather an infinitive like בּלעי in Job 7:19, since ארחי is undoubtedly not inflected from ארח, but, as being infinitive, like עברי in Deu 4:21, from ארח; and the verb ארח also, with the exception of this passage, only occurs in the speeches of Elihu (Job 34:8), which are almost more strongly Aramaizing than the Book of Job itself. Further, as an Aramaizing feature we have the objective relation marked by Lamed in the expression בּנתּה לרעי, Thou understandest my thinking, as in Psa 116:16; Psa 129:3; Psa 135:11; Psa 136:19. The monostichic opening is after the Davidic style, e.g., Psa 23:1. Among the prophets, Isaiah in particular is fond of such thematic introductions as we have here in Psa 139:1. On ותּדע instead of ותּדעני vid., on Psa 107:20; the pronominal object stands once beside the first verb, or even beside the second (Kg2 9:25), instead of twice (Hitzig). The "me" is then expanded: sitting down, rising up, walking and lying, are the sum of human conditions or states. רעי is the totality or sum of the life of the spirit and soul of man, and דּרכי the sum of human action. The divine knowledge, as ותּדע says, is the result of the scrutiny of man. The poet, however, in Psa 139:2 and Psa 139:3 uses the perfect throughout as a mood of that which is practically existing, because that scrutiny is a scrutiny that is never unexecuted, and the knowledge is consequently an ever-present knowledge. מרחוק is meant to say that He sees into not merely the thought that is fully fashioned and matured, but even that which is being evolved. זרית from זרה is combined by Luther (with Azulai and others) with זר, a wreath (from זרר, constringere, cingere), inasmuch as he renders: whether I walk or lie down, Thou art round about me (Ich gehe oder lige, so bistu umb mich). זרה ought to have the same meaning here, if with Wetzstein one were to compare the Arabic, and more particularly Beduin, drrâ, dherrâ, to protect; the notion of affording protection does not accord with this train of thought, which has reference to God's omniscience: what ought therefore to be meant is a hedging round which secures its object to the knowledge, or even a protecting that places it in security against any exchanging, which will not suffer the object to escape it.

(Note: This Verb. tert. Arab. w et y is old, and the derivative dherâ, protection, is an elegant word; with reference to another derivative, dherwe, a wall of rock protecting one from the winds, vid., Job, at Job 24:7, note. The II form (Piel) signifies to protect in the widest possible sense, e.g., (in Neshwn, ii. 343b), "[Arab.] drâ 'l-šâh, he protected the sheep (against being exchanged) by leaving a lock of wool upon their backs when they were shorn, by which they might be recognised among other sheep.")

The Arabic ḏrâ, to know, which is far removed in sound, is by no means to be compared; it is related to Arab. dr', to push, urge forward, and denotes knowledge that is gained by testing and experimenting. But we also have no need of that Arab. ḏrâ, to protect, since we can remain within the range of the guaranteed Hebrew usage, inasmuch as זרה, to winnow, i.e., to spread out that which has been threshed and expose it to the current of the wind, in Arabic likewise ḏrrâ, (whence מזרה, midhrâ, a winnowing-fork, like רחת, racht, a winnowing-shovel), gives an appropriate metaphor. Here it is equivalent to: to investigate and search out to the very bottom; lxx, Symmachus, and Theodotion, ἐξιξηνίασας, after which the Italic renders investigasti, and Jerome eventilasti. הסכּין with the accusative, as in Job 22:21 with עם: to enter into neighbourly, close, familiar relationship, or to stand in such relationship, with any one; cogn. שׁכן, Arab. skn. God is acquainted with all our ways not only superficially, but closely and thoroughly, as that to which He is accustomed.

In Psa 139:4 this omniscience of God is illustratively corroborated with כּי; Psa 139:4 has the value of a relative clause, which, however, takes the form of an independent clause. מלּה (pronounced by Jerome in his letter to Sunnia and Fretela, 82, MALA) is an Aramaic word that has been already incorporated in the poetry of the Davidico-Salomonic age. כלּהּ signifies both all of it and every one. In Psa 139:5 Luther has been misled by the lxx and Vulgate, which take צוּר in the signification formare (whence צוּרה, forma); it signifies, as the definition "behind and before" shows, to surround, encompass. God is acquainted with man, for He holds him surrounded on all sides, and man can do nothing, if God, whose confining hand he has lying upon him (Job 9:23), does not allow him the requisite freedom of motion. Instead of דּעתּך (XX ἡ γνῶσίς σου) the poet purposely says in Psa 139:6 merely דּעת: a knowledge, so all-penetrating, all-comprehensive as God's knowledge. The Ker reads פּליאה, but the Chethb פּלאיּה is supported by the Chethb פּלאי in Jdg 13:18, the Ker of which there is not פּליא, but פּלי (the pausal form of an adjective פּלי, the feminine of which would be פּליּה). With ממּנּי the transcendence, with נשׂגּבה the unattainableness, and with להּ לא־אוּכל the incomprehensibleness of the fact of the omniscience of God is expressed, and with this, to the mind of the poet, coincides God's omnipresence; for true, not merely phenomenal, knowledge is not possible without the immanence of the knowing one in the thing known. God, however, is omnipresent, sustaining the life of all things by His Spirit, and revealing Himself either in love or in wrath - what the poet styles His countenance. To flee from this omnipresence (מן, away from), as the sinner and he who is conscious of his guilt would gladly do, is impossible. Concerning the first אנּה, which is here accented on the ultima, vid., on Psa 116:4.

Matthew Henry

On Psalms 139:1-6

David here lays down this great doctrine, That the God with whom we have to do has a perfect knowledge of us, and that all the motions and actions both of our inward and of our outward man are naked and open before him.

I. He lays down this doctrine in the way of an address to God; he says it to him, acknowledging it to him, and giving him the glory of it. Divine truths look fully as well when they are prayed over as when they are preached over, and much better than when they are disputed over. When we speak of God to him himself we shall find ourselves concerned to speak with the utmost degree both of sincerity and reverence, which will be likely to make the impressions the deeper.

II. He lays it down in a way of application to himself, not, "Thou hast known all," but, "Thou hast known me; that is it which I am most concerned to believe and which it will be most profitable for me to consider." Then we know these things for our good when we know them for ourselves, Job 5:27. When we acknowledge, "Lord, all souls are thine," we must add, "My soul is thine; thou that hatest all sin hatest my sin; thou that art good to all, good to Israel, art good to me." So here, "Thou hast searched me, and known me; known me as thoroughly as we know that which we have most diligently and exactly searched into." David was a king, and the hearts of kings are unsearchable to their subjects (Pro 25:3), but they are not so to their Sovereign.

III. He descends to particulars: "Thou knowest me wherever I am and whatever I am doing, me and all that belongs to me." 1. "Thou knowest me and all my motions, my down-sitting to rest, my up-rising to work, with what temper of mind I compose myself when I sit down and stir up myself when I rise up, what my soul reposes itself in as its stay and support, what it aims at and reaches towards as its felicity and end. Thou knowest me when I come home, how I walk before my house, and when I go abroad, on what errands I go." 2. "Thou knowest all my imaginations. Nothing is more close and quick than thought; it is always unknown to others; it is often unobserved by ourselves, and yet thou understandest my thought afar off. Though my thoughts be ever so foreign and distant from one another, thou understandest the chain of them, and canst make out their connexion, when so many of them slip my notice that I myself cannot." Or, "Thou understandest them afar off, even before I think them, and long after I have thought them and have myself forgotten them." Or, "Thou understandest them from afar; from the height of heaven thou seest into the depths of the heart," Psa 33:14. 3. "Thou knowest me and all my designs and undertakings; thou compassest every particular path; thou siftest (or winnowest) my path" (so some), "so as thoroughly to distinguish between the good and evil of what I do," as by sifting we separate between the corn and the chaff. All our actions are ventilated by the judgment of God, Psa 17:3. God takes notice of every step we take, every right step and every by-step. He is acquainted with all our ways, intimately acquainted with them; he knows what rule we walk by, what end we walk towards, what company we walk with. 4. "Thou knowest me in all my retirements; thou knowest my lying down; when I am withdrawn from all company, and am reflecting upon what has passed all day and composing myself to rest, thou knowest what I have in my heart and with what thought I go to bed." 5. "Thou knowest me, and all I say (Psa 139:4): There is not a word in my tongue, not a vain word, nor a good word, but thou knowest it altogether, knowest what it meant, from what thought it came, and with what design it was uttered. There is not a word at my tongue's end, ready to be spoken, yet checked and kept in, but thou knowest it." When there is not a word in my tongue, O Lord! thou knowest all (so some read it); for thoughts are words to God. 6. "Thou knowest me in every part of me: Thou hast beset me behind and before, so that, go which way I will, I am under thy eye and cannot possibly escape it. Thou hast laid thy hand upon me, and I cannot run away from thee." Wherever we are we are under the eye and hand of God. perhaps it is an allusion to the physician's laying his hand upon his patient to feel how his pulse beats or what temper he is in. God knows us as we know not only what we see, but what we feel and have our hands upon. All his saints are in his hand.

IV. He speaks of it with admiration (Psa 139:6): It is too wonderful for me; it is high. 1. "Thou hast such a knowledge of me as I have not of myself, nor can have. I cannot take notice of all my own thoughts, nor make such a judgment of myself as thou makest of me."? 2. "It is such a knowledge as I cannot comprehend, much less describe. That thou knowest all things I am sure, but how I cannot tell." We cannot by searching find out how God searches and finds out us; nor do we know how we are known.

Spurgeon's Treasury of David

Thou compassest my path and my lying down. My path and my pallet, my running and my resting, are alike within the circle of thine observation. Thou dost surround me even as the air continually surrounds all creatures that live. I am shut up within the wall of thy being; I am encircled within the bounds of thy knowledge. Waking or sleeping I am still observed of thee. I may leave thy path, but you never leave mine. I may sleep and forget thee, but thou dost never slumber, nor fall into oblivion concerning thy creature. The original signifies not only surrounding, but winnowing and sifting. The Lord judges our active life and our quiet life; he discriminates our action and our repose, and marks that in them which is good and also that which is evil. There is chaff in all our wheat, and the Lord divides them with unerring precision. And art acquainted with all my ways. Thou art familiar with all I do; nothing is concealed from thee, nor surprising to thee, nor misunderstood by thee. Our paths may be habitual or accidental, open or secret, but with them all the Most Holy One is well acquainted. This should fill us with awe, so that we sin not; with courage, so that we fear not; with delight, so that we mourn not.
