1 Samuel 20:3; 1 Samuel 25:34

1 Samuel 20:3

3 But David took an oath and said, “Your father knows very well that I have found favor in your eyes, and he has said to himself, ‘Jonathan must not know this or he will be grieved.’ Yet as surely as the LORD lives and as you live, there is only a step between me and death.”

1 Samuel 25:34

34 Otherwise, as surely as the LORD, the God of Israel, lives, who has kept me from harming you, if you had not come quickly to meet me, not one male belonging to Nabal would have been left alive by daybreak.”
