And when Samuel rose early to meet Saul in the morning, it was told Samuel, saying, Saul came to Carmel, and, behold, he set him up a place, and is gone about, and passed on, and gone down to Gilgal. He set him up a place - Literally, a hand, יד yad. Some say it was a monument; others, a triumphal arch: probably it was no more than a hand, pointing out the place where Saul had gained the victory. Absalom's pillar is called the hand of Absalom, 2 Samuel 18:18.
