Numbers 3:41

41 and thou shalt take the Levites to me for all the first begotten of the sons of Israel; I am the Lord; and thou shalt take their beasts (to me) for all the first begotten of the sons of Israel. (and thou shalt give me the Levites in place of all the first-born sons of the Israelites; I am the Lord; and thou shalt give me the beasts of the Levites in place of all the first-born male beasts of the Israelites.)

Numbers 3:41 Meaning and Commentary

Numbers 3:41

And thou shall take the Levites for me
For his service, to minister to his priests, and serve in his tabernacle:

I [am] the Lord;
who has a right to all, and can claim who he pleases for himself in a special manner, and therefore could and did take the Levites to himself:

instead of the firstborn among the children of Israel;
these he had taken to him before, and ordered to be sanctified unto him, and for whom a redemption price was paid to his priests for the support of them, and the tabernacle service, and now it was his will to make an exchange of these for the Levites:

and the cattle of the Levites, instead of all the firstling among the
cattle of the children of Israel:
every firstling of clean cattle was the Lord's, and given to his priests, and the firstlings of unclean cattle were redeemed with a lamb, and which were given to the same; and now instead of these he requires the cattle of the Levites; not that they should be deprived of their use of them, or that they should be taken and sacrificed, but that they should be with them devoted to him, and they should possess them in his right.

Numbers 3:41 In-Context

39 All the Levites, which Moses and Aaron numbered, by the commandment of the Lord, by their families, in male kind, from one month and above, were two and twenty thousand. (And the number of all the Levites, whom Moses and Aaron listed, or registered, by the Lord's command, by their families, all the males from one month of age and older, was twenty-two thousand.)

40 And the Lord said to Moses, Number thou the first begotten of male kind of the sons of Israel, from one month and above (from one month of age and older); and thou shalt have the sum, or the number, of them;

41 and thou shalt take the Levites to me for all the first begotten of the sons of Israel; I am the Lord; and thou shalt take their beasts (to me) for all the first begotten of the sons of Israel. (and thou shalt give me the Levites in place of all the first-born sons of the Israelites; I am the Lord; and thou shalt give me the beasts of the Levites in place of all the first-born male beasts of the Israelites.)

42 And as the Lord commanded, Moses numbered the first begotten (male) children of the sons of Israel;

43 and the males were by their names, from one month and above, two and twenty thousand two hundred and seventy and three. (and the number of the males, listed by their names, from one month of age and older, was twenty-two thousand and two hundred and seventy-three.)
