'Commandment of the Lord' in the Bible

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

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.

And Samuel said to Saul, You have done foolishly: you have not kept the commandment of the LORD your God, which he commanded you: for now would the LORD have established your kingdom upon Israel forever.

And Samuel came to Saul: and Saul said unto him, Blessed be you of the LORD: I have performed the commandment of the LORD.

And Saul said unto Samuel, I have sinned: for I have transgressed the commandment of the LORD, and your words: because I feared the people, and obeyed their voice.
