1 Samuel 23:6 CEV

[6] Meanwhile, Saul heard that David was in Keilah. "God has let me catch David," Saul said. "David is trapped inside a walled town where the gates can be locked." Saul decided to go there and surround the town, in order to trap David and his men. He sent messengers who told the towns and villages, "Send men to serve in Saul's army!" By this time, Abiathar had joined David in Keilah and had brought along everything he needed to get answers from God.
