'Obey' in the Bible

Wherefore then didst thou not obey the voice of Jehovah, but didst fly upon the spoil, and didst that which was evil in the sight of Jehovah?

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