And they raised over him a great heap of stones unto this day. So the LORD turned from the fierceness of his anger. Wherefore the name of that place was called, The valley of Achor, unto this day.
They raised over him a great head of stones. It is customary to raise cairns over the graves of criminals or infamous persons in the East still. Every honest Arab, on passing the grave of a robber, indicates his detestation of the crime and its perpetrator by adding a stone to the cairn (cf. Joshua 8:29; 2 Samuel 18:17).
Called, The valley of Achor (trouble), unto this day. So painful an episode would give notoriety to the spot; and it is more than once noticed by the sacred writers of a later age (Isaiah 65:10; Hosea 2:15). It is the same as in latter age was known as "the brook Cherith, that is before Jordan" (see the note at 1 Kings 17:1-7), now Wady el-Kelt.
