Deuteronomy 33:4
Ver. 4. Moses commanded us a law,.... The law was of God, it came forth from his right hand, De 33:2; it is of his enacting, a declaration of his will, and has his authority stamped upon it, who is the lawgiver, and which lays under obligation to regard it; but it was delivered to Moses, and by him to the children of Israel, on whom he urged obedience to it; and so it is said to come by him, and sometimes is called the law of Moses, see Joh 1:17;
[even] the inheritance of the congregation of Jacob; which either describes the persons who were commanded to keep the law, the tribes of Jacob or congregation of Israel, who were the Lord's people, portion, and inheritance, De 32:9; or the law commanded, which was to be valued, not only as a peculiar treasure, but to be considered a possession, an estate, an inheritance, to be continued among them, and to be transmitted to their posterity, see Ps 119:111; these are the words of the people of Israel, and therefore are thus prefaced in the Targums of Jonathan and Jerusalem,
"the children of Israel said, Moses commanded, &c.''
they were represented by Moses.
