Absalom used to rise early and stand beside the road into the gate; and when anyone brought a suit before the king for judgment, Absalom would call out and say, "From what city are you?" When the person said, "Your servant is of such and such a tribe in Israel,"
Absalom would say, "See, your claims are good and right; but there is no one deputed by the king to hear you."
Absalom said moreover, "If only I were judge in the land! Then all who had a suit or cause might come to me, and I would give them justice."
Whenever people came near to do obeisance to him, he would put out his hand and take hold of them, and kiss them.
Thus Absalom did to every Israelite who came to the king for judgment; so Absalom stole the hearts of the people of Israel.
At the end of four years Absalom said to the king, "Please let me go to Hebron and pay the vow that I have made to the Lord.
