'Voice of the Lord' in the Bible

But if you will not listen to the voice of the LORD, but rebel against the commandment of the LORD, then will the hand of the LORD be against you, and against your king.

Why then did you not obey the voice of the LORD, but took the spoils, and did that which was evil in the sight of the LORD?"

Saul said to Samuel, "But 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.

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 listen than the fat of rams.

Because you did not obey the voice of the LORD, and did not execute his fierce wrath on Amalek, therefore the LORD has done this thing to you this day.
