Deuteronomy 34:4-6

Then the LORD said to him, “This is the land of which I swore to give Abraham, Isaac, and Jacob, saying, ‘I will give it to your descendants.’ I have caused you to see it with your eyes, but you shall not cross 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 a valley in the land of Moab, opposite Beth Peor; but no one knows his grave to this day.
