1 Samuel 23:16-18

Young's Literal Translation

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.'

¹⁸ And they make a covenant both of them before Jehovah; and David abideth in the forest, and Jonathan hath gone to his house.
