'Obey' in the Bible

Nevertheless the people refused to obey the voice of Samuel; and they said, Nay; but we will have a king over us;

If ye will fear the LORD, and serve him, and obey his voice, and not rebel against the commandment of the LORD, then shall both ye and also the king that reigneth over you continue following the LORD your God:

But if ye will not obey the voice of the LORD, but rebel against the commandment of the LORD, then shall the hand of the LORD be against you, as it was against your fathers.

Wherefore 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.
