Targum zu Dewarim 34:6

Blessed be the Name of the Lord of the world, who hath taught us His righteous way. He hath taught us to clothe the naked, as He clothed Adam and Hava; He hath taught us to unite the bridegroom and the bride in marriage, as He united Hava to Adam. He hath taught us to visit the sick, as He revealed Himself to Abraham when he was ill, from being circumcised; He hath taught us to console the mourners, as He revealed Himself again to Jakob when returning from Padan, in the place where his mother had died. He hath taught us to feed the poor, as He sent Israel bread from heaven; He hath taught us to bury the dead by (what He did for) Mosheh; for He revealed Himself in His Word, and with Him the companies of ministering angels. Michael and Gabriel spread forth the golden bed, fastened with chrysolites, gems, and beryls, adorned with hangings of purple silk, and satin, and white linens. Metatron, Jophiel, and Uriel, and Jephephya, the wise sages, laid him upon it, and by His Word He conducted him four miles, and buried him in the valley opposite Beth Peor; that Israel, as oft as they look up to Peor, may have the memory of their sin; and at sight of the burying place of Mosheh may be humbled: but no man knoweth his sepulchre unto this day.

And He buried him in a valley in the land of the Moabaee, opposite to the idol Peor; nor knoweth any one his sepulchre unto this day.
