Deuteronomy 34:6-8

American Standard Version

⁶ And ^[a]he buried him in the valley in the land of Moab over against Beth-peor: but no man knoweth of his sepulchre unto this day. ⁷ And Moses was a hundred and twenty years old when he died: his eye was not dim, nor his natural force abated. ⁸ And the children of Israel wept for Moses in the plains of Moab thirty days: so the days of weeping in the mourning for Moses were ended.
