2 Samuel 18
17 Ref And they took Absalom's body and put it into a great hole in the wood, and put a great mass of stones over it: and every man of Israel went in flight to his tent.
18 Ref Now Absalom, before his death, had put up for himself a pillar in the king's valley, naming it after himself; for he said, I have no son to keep my name in memory: and to this day it is named Absalom's pillar.
