'Law' in the Bible

The law of truth was in his mouth, and unrighteousness was not found in his lips: he walked with me in peace and uprightness, and he turned many from iniquity.

For the priest's lips should keep knowledge, and at his mouth they seek the law; for he is the messenger of Jehovah of hosts.

But ye are departed out of the way; ye have caused many to stumble at the law; ye have corrupted the covenant of Levi, saith Jehovah of hosts.

And I also have made you contemptible and base before all the people, because ye have not kept my ways, but have respect of persons in administering the law.

Remember the law of Moses my servant, which I commanded unto him in Horeb for all Israel, the statutes and ordinances.
