1 Samuel 20:2-3

"And he said unto him, God forbid; thou shalt not die: behold, my father will do nothing either great or small, but that he will show it me: and why should my father hide this thing from me? it is not so. And David sware moreover, and said, Thy father certainly knoweth that I have found grace in thine eyes; and he saith, Let not Jonathan know this, lest he be grieved: but truly as the LORD liveth, and as thy soul liveth, there is but a step between me and death" - 1 Samuel 20:2-3 KJV
