1 Samuel 23:18

16Jonathan, Saul’s son, arose and went to David into the woods, and strengthened his hand in God.

17He said to him, “Don’t be afraid, for the hand of Saul my father won’t find you; and you will be king over Israel, and I will be next to you; and Saul my father knows that also.”

18They both made a covenant before the LORD. Then David stayed in the woods and Jonathan went to his house.

19Then the Ziphites came up to Saul to Gibeah, saying, “Doesn’t David hide himself with us in the strongholds in the woods, in the hill of Hachilah, which is on the south of the desert?

20Now therefore, O king, come down. According to all the desire of your soul to come down; and our part will be to deliver him up into the king’s hand.”
