1 Samuel 20:2-4

Darby Translation

² And he said to him, God forbid; thou shalt not die: behold, my father will do nothing either great or small, and not apprise me; and why should my father hide this thing from me? it is not so.

³ And David swore again and again, and said, Thy father certainly knows that I have found favour in thy sight: and he has thought, Jonathan shall not know this, lest he be grieved; but truly [as] Jehovah liveth, and [as] thy soul liveth, there is but a step between me and death.

⁴ And Jonathan said to David, What thy soul may say, I will even do it for thee.
