'Voice of the Lord' in the Bible

But if you 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.

Why then did you not obey the voice of the LORD, but did pounce upon the spoil, and did evil in the sight of the LORD?

And Saul said unto Samuel, Yea, I have obeyed the voice of the LORD, and have gone the way which the LORD sent me, and have brought Agag the king of Amalek, and have utterly destroyed the Amalekites.

And Samuel said, has 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 you obeyed not the voice of the LORD, nor executed his fierce wrath upon Amalek, therefore has the LORD done this thing unto you this day.
