Deuteronomy 34:5-7

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 Beth-peor: but no man knoweth of his sepulchre unto this day. And Moses was an hundred and twenty years old when he died: his eye was not dim, nor his natural force abated.
