1 Samuel 15:13

Blessed be thou of the Lord; I thank thee, and I beg that God would bless thee, for sending me upon this employment, and giving me this opportunity of manifesting my obedience to God. I have performed the commandment of the Lord, to wit, for the main and substance of it, to wit, the extirpation of that wicked people; for he thought the sparing of Agag and the cattle very inconsiderable in the case, though indeed it was expressly contrary to God's command; but self-interest made him exceeding partial in his own cause: or else, like a bold hypocrite, he pretends that for his part he had obeyed God; resolving, it seems, to cast the blame upon the people, as he did.
