1 Samuel 20:14
But if my father intends to do you harm, may the LORD do so to me and more also if I do not disclose it to you and send you away in safety — Jonathan's oath (*v'im ratze avi le'rasah v'lo agid le'cha*) reverses the conditional: if Saul intends harm, Jonathan binds himself by curse to inform David. The *v'tzeitach b'shalom*, send you away in safety, commits Jonathan to David's escape, his physical safety transcending familial obligation.
