1 Samuel 23:15-17

Young's Literal Translation

¹⁵ And David seeth that Saul hath come out to seek his life, and David [is] in the wilderness of Ziph, in a forest.

¹⁶ And Jonathan son of Saul riseth, and goeth unto David to the forest, and strengtheneth his hand in God,

¹⁷ and saith unto him, `Fear not, for the hand of Saul my father doth not find thee, and thou dost reign over Israel, and I am to thee for second, and also so knoweth Saul my father.'
