'Commandment' in the Bible

If ye will fear Jehovah, and serve him, and hearken unto his voice, and not rebel against the commandment of Jehovah, and both ye and also the king that reigneth over you be followers of Jehovah your God, well :

but if ye will not hearken unto the voice of Jehovah, but rebel against the commandment of Jehovah, then will the hand of Jehovah be against you, as it was against your fathers.

And Samuel said to Saul, Thou hast done foolishly; thou hast not kept the commandment of Jehovah thy God, which he commanded thee: for now would Jehovah have established thy kingdom upon Israel for ever.

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

And Saul said unto Samuel, I have sinned; for I have transgressed the commandment of Jehovah, and thy words, because I feared the people, and obeyed their voice.
