Once the three of the thirty chiefs went down and came to David at the cave of Adullam during the harvest, while a troop of Philistines was camping in the Valley of Rephaim.
while the Philistines had raided the towns in the foothills and in the South of Judah. They captured and occupied Beth-shemesh, Aijalon and Gederot, as well as Soho, Timnah and Gimzo with their villages.
So David walked from there and escaped to the cave of Adullam. When his brothers and all his father’s house heard about it, they went down there to him.
