Deuteronomy 34:6-8

New King James Version

⁶ And He buried him in a valley in the land of Moab, opposite Beth Peor; but ^(A)no one knows his grave to this day. ^7 (B)Moses was one hundred and twenty years old when he died. ^(C)His ^[a]eyes were not dim nor his natural vigor ^[b]diminished. ⁸ And the children of Israel wept for Moses in the plains of Moab ^(D)thirty days. So the days of weeping and mourning for Moses ended.
