Deuteronomy 34:4-6

Then the LORD said to him, “This is the land which I swore to Abraham, Isaac, and Jacob, saying, ‘I will give it to your descendants’; I have let you see it with your eyes, but you shall not go over there.” 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 the valley in the land of Moab, opposite Beth-peor; but no man knows his burial place to this day.
