Deuteronomy 33:4 - Joseph Benson’s Commentary on the Old and New Testaments

Moses commanded us a law Moses has been thought by some to speak this of himself, in the third person, because he intended the contents of this chapter, like the preceding song, to be learned by the Israelites, and repealed in their own persons. They are therefore supposed to say, Moses commanded us a law, &c. The inheritance of the congregation The law is called their inheritance. because the obligation to observe it was hereditary, passing from parents to their children, and because this was the best part of their inheritance, the greatest of all those gifts which God bestowed upon them. So the psalmist thought, “Thy testimonies have I taken as a heritage for ever,” Psalms 119:111.
