'Commandment' in the Bible

If you will fear Yahweh, and serve him, and listen to his voice, and not rebel against the commandment of Yahweh, and both you and also the king who reigns over you are followers of Yahweh your God, [well]:

but if you will not listen to the voice of Yahweh, but rebel against the commandment of Yahweh, then will the hand of Yahweh be against you, as it was against your fathers.

Samuel said to Saul, "You have done foolishly. You have not kept the commandment of Yahweh your God, which he commanded you; for now Yahweh would have established your kingdom on Israel forever.

Samuel came to Saul; and Saul said to him, "You are blessed by Yahweh! I have performed the commandment of Yahweh."

Saul said to Samuel, "I have sinned; for I have transgressed the commandment of Yahweh, and your words, because I feared the people, and obeyed their voice.
