1 Samuel 23:18-20

And the two of them made a covenant before the LORD. David remained at Horesh, and Jonathan went home. Then the Ziphites went up to Saul at Gibeah, saying, “Is not David hiding among us in the strongholds at Horesh, on the hill of Hachilah, which is south of Jeshimon? Now come down, O king, according to all your heart’s desire to come down, and our part shall be to surrender him into the king’s hand.”
