1st Samuel 23:18

15 And David saw that Saul was come out to seek his life: and David was in the wilderness of Ziph in the wood.

16 And Jonathan, Saul`s son, arose, and went to David into the wood, and strengthened his hand in God.

17 And he said unto him, Fear not; for the hand of Saul my father shall not find thee; and thou shalt be king over Israel, and I shall be next unto thee; and that also Saul my father knoweth.

18 And they two made a covenant before Jehovah: and David abode in the wood, and Jonathan went to his house.

19 Then came up the Ziphites to Saul to Gibeah, saying, Doth not David hide himself with us in the strongholds in the wood, in the hill of Hachilah, which is on the south of the desert?

20 Now therefore, O king, come down, according to all the desire of thy soul to come down; and our part shall be to deliver him up into the king`s hand.

21 And Saul said, Blessed be ye of Jehovah; for ye have had compassion on me.
