Why then didst thou not obey the voice of the LORD, but didst fly upon the spoil, and didst evil in the sight of the LORD?

And Samuel said, Hath the LORD as great delight in burnt-offerings and sacrifices, as in obeying the voice of the LORD? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.

Because thou didst not obey the voice of the LORD, nor execute his fierce wrath upon Amalek, therefore hath the LORD done this thing to thee this day.
