Absalom had sheepshearers at Baal-hazor, which is near Ephraim. (2 Samuel 13:23)
Absalom murders Amnon at Baal-hazor
After 2 years, he had sheepshearers at Baal-hazor and invited all the king's sons. Absalom came to King David and said, "Behold, your servant has sheepshearers. Please let the king and his servants go with your servant." But David declined. Absalom pressed him, but he would not go but gave his blessing. "If not, please let my brother Amnon go with us." The king said, "Why should he go with you?" But Absalom pressed him until he let Amnon and all the king's sons go with him. Absalom commanded his servants, "Mark when Amnon's heart is merry with wine, and when I say to you, 'Strike Amnon,' then kill him. Do not fear; have I not commanded you? Be courageous and be valiant." So his servants killed him, and all the sons arose and fled on their mules.
Absalom fled to Talmai the son of Ammihud, king of Geshur and stayed there for 3 years.
