I would add to the above explanation that Saul was offering a sacrifice while being in rebellion to the command to kill everyone and destroy the spoil. 1Sa 15:3 Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.' This should be a warning to us that we can't offer sacrifice while in rebellion and expect it to be accepted.
