1 Samuel 20:3-4

New King James Version

³ Then David took an oath again, and said, “Your father certainly knows that I have found favor in your eyes, and he has said, ‘Do not let Jonathan know this, lest he be grieved.’ But ^(A)truly, as the Lord lives and as your soul lives, there is but a step between me and death.”

⁴ So Jonathan said to David, “Whatever you yourself desire, I will do it for you.”
