I Samuel 23:18-20

So the two of them made a covenant before the LORD. And David stayed in the woods, and Jonathan went to his own house. Then the Ziphites came up to Saul at Gibeah, saying, “Is David not hiding with us in strongholds in the woods, in the hill of Hachilah, which is on the south of Jeshimon? Now therefore, O king, come down according to all the desire of your soul to come down; and our part shall be to deliver him into the king’s hand.”
