Deuteronomy 34:5-9

So Moses the servant of the Lord died there in the land of Moab, in accordance with the word of the Lord.

And He buried him in the valley in the land of Moab, opposite Beth-peor; but no one knows his burial place to this day.

Although Moses was 120 years old when he died, his eyesight was not dim, nor had his vigor left him.

So the sons of Israel wept for Moses in the plains of Moab for thirty days; then the days of weeping and mourning for Moses came to an end.

Now Joshua the son of Nun was filled with the spirit of wisdom, because Moses had laid his hands on him; and the sons of Israel listened to him and did as the Lord had commanded Moses.
