'Command of the Lord' in the Bible

If you will fear the Lord and serve Him, and listen to His voice and not rebel against the command of the Lord, then both you and also the king who reigns over you will follow the Lord your God.

If you will not listen to the voice of the Lord, but rebel against the command of the Lord, then the hand of the Lord will be against you, as it was against your fathers.

Samuel came to Saul, and Saul said to him, “Blessed are you of the Lord! I have carried out the command of the Lord.”

Then Saul said to Samuel, “I have sinned; I have indeed transgressed the command of the Lord and your words, because I feared the people and listened to their voice.
