1 Samuel 18:17

Her will I give thee to wife: this was no more than Saul was obliged to do by his former promise, 1 Samuel 17:25, which here he renews and pretends to perform, though he intended nothing less, as the sequel shows; whereby he makes himself guilty of ingratitude, injustice, and breach of trust, and withal of gross hypocrisy. Let the hand of the Philistines be upon him; he thought so great an offer would oblige him, who was of himself valiant enough to give proofs of more than common valour, and to venture upon the most dangerous enterprises.
