Behold, this day your eyes have seen how that Yahweh had delivered you today into my hand in the cave: and some bade me kill you; but [my eye] spared you; and I said, I will not put forth my hand against my lord; for he is Yahweh's anointed.
Swear now therefore by the Lord, that you will not cut off my children after me, and that you will not destroy my name out of my father's house. And so David sware unto Saul. And Saul went home; but David and his men went into the hold ( 1 Samuel 24:21-22 ). "
