And Moses wrote this law, and delivered it unto the priests the sons of Levi. Deuteronomy 31:9
These be the words which Moses spake unto all Israel on this side Jordan in the wilderness. Deuteronomy 1:1
Now the man Moses was very meek, above all the men which were upon the face of the earth. Numbers 12:3Observed and described his own death and burial. And then said that no one knows exactly where he was buried "to this day." (Implying that this passage was written long after Moses died.)
So Moses the servant of the LORD died there in the land of Moab, according to the word of the LORD. And he buried him in a valley in the land of Moab, over against Bethpeor: but no man knoweth of his sepulchre unto this day. Deuteronomy 34:5-6And unless Moses claimed to be be greatest prophet, saying there hasn't been as great a prophet ever since.
And there arose not a prophet since in Israel like unto Moses, whom the LORD knew face to face. Deuteronomy 34:10
