Charles Ellicott Commentary Deuteronomy 29:2

"And Moses called unto all Israel, and said unto them, Ye have seen all that Jehovah did before your eyes in the land of Egypt unto Pharaoh, and unto all his servants, and unto all his land;" — Deuteronomy 29:2 (ASV)

And Moses called all Israel and said to them. —The address in this chapter may be compared with that of Joshua to the people (as distinct from their heads and officers) in Joshua 24. The topics brought before them are simple: in Deuteronomy 29:2-3, the miracles of the Exodus; in Deuteronomy 29:5 and Deuteronomy 29:7, the wilderness journey; and in Deuteronomy 29:7-8, the conquest of Sihon and Og. All are appealed to, from the captains of the tribes (Deuteronomy 29:10), to the little ones (Deuteronomy 29:11), and the lowest slaves (Deuteronomy 29:11). And the point set before them is one simple thing: to accept Jehovah as their God. All this is very closely reproduced in Joshua 24 (see Notes in that place).

You have seen. —The pronoun is emphatic. You yourselves are witnesses. I need not repeat the story. (Compare Deuteronomy 11:2-7.)
