1 Samuel 18:2-4

Young's Literal Translation

² And Saul taketh him on that day, and hath not permitted him to turn back to the house of his father.

³ And Jonathan maketh -- also David -- a covenant, because he loveth him as his own soul,

⁴ and Jonathan strippeth himself of the upper robe which [is] upon him, and giveth it to David, and his long robe, even unto his sword, and unto his bow, and unto his girdle.
