John Gill

On Numbers 1:44

These are those that were numbered,.... Or, as the Targum of Jonathan, these are the sums of the numbers; namely, those before given of the several respective tribes:

which Moses and Aaron numbered, and the princes of Israel, being twelve men; for though the tribe of Levi was not numbered, yet Joseph having a double portion, his two sons are reckoned as distinct tribes; so that one out of each tribe made up the number twelve:

each one for the house of his fathers; for the tribe he belonged to, with which it might reasonably be supposed he was best acquainted, and could more readily take the number of them.

Keil & Delitzsch

On Numbers 1:17-47

This command was carried out by Moses and Aaron. They took for this purpose the twelve heads of tribes who are pointed out (see at Lev 24:11) by name, and had the whole congregation gathered together by them and enrolled in genealogical tables. התילּד, to announce themselves as born, i.e., to have themselves entered in genealogical registers (books of generations). This entry is called a פּקד, mustering, in Num 1:19, etc. In vv. 20-43 the number is given of those who were mustered of all the different tribes, and in Num 1:44-47 the total of the whole nation, with the exception of the tribe of Levi. "Their generations" (Num 1:20, Num 1:22, Num 1:24, etc.), i.e., those who were begotten by them, so that "the sons of Reuben, Simeon," etc., are mentioned as the fathers from whom the mishpachoth and fathers' houses had sprung. The ל before שׁמעון בּני in Num 1:22, and the following names (in Num 1:24, Num 1:26, etc.), signifies "with regard to" (as in Isa 32:1; Psa 17:4, etc.).

Matthew Henry

On Numbers 1:44-46

We have here the sum total at the foot of the account; they were in all 600,000 fighting men, and 3550 over. Some think that when this was their number some months before (Exo 38:26) the Levites were reckoned with them, but now that tribe was separated for the service of God, yet so many more had by this time attained to the age of twenty years as that still they were the same number, to show that whatever we part with for the honour and service of God it shall certainly be made up to us one way of other. Now we see what a vast body of men they were. Let us consider, 1. How much went to maintain all these (besides twice as many more, no question, of women and children, sick and aged, and the mixed multitude) for forty years together in the wilderness; and they were all at God's finding every day, having their food from the dew of heaven, and not from the fatness of the earth. O what a great and good housekeeper is our God, that has such numbers depending on him and receiving from him every day! 2. What work sin makes with a people; within forty years most of them would indeed have died of course for the common sin of mankind; for, when sin entered into the world, death came with it, and how great are the desolations which it makes in the earth! But, for the particular sin of unbelief and murmuring, all those that were now numbered, except two, laid their bones under their iniquity, and perished in the wilderness. 3. What a great multitude God's spiritual Israel will amount to at last; though at one time, and in one place, they seem to be but a little flock, yet when they come all together they shall be a great multitude, innumerable, Rev 7:9. And, though the church's beginning be small, its latter end shall greatly increase. A little one shall become a thousand.
