1 Samuel 15:20

Yea, I have obeyed... — These and the words which follow are simply a repetition of the king’s former excuse for his act: but they show us what was the state of Saul’s mind: he evidently disbelieved in the power of the Eternal as a heart reader. If he could justify himself before Samuel, that was all he cared for. He asserted his own integrity of purpose and his great zeal for the public sacrifice to God, knowing all the while that low earthly reasons had been the springs of his conduct. He reiterated the plea that what he had done was in accordance with the voice of the people, conscious all the while that the plea was false.
