To order or direct with urgency; to admonish or instruct with authority; to command. Says Johnson, “this word is more authoritative than direct, and less imperious than command.” It has the force of pressing admonition with authority; as, a parent enjoins on his children the duty of obedience. But it has also the sense of command; as the duties enjoined by God in the moral law.

In law, to forbid judicially; to issue or direct a legal injunction to stop proceedings. This is a suit to enjoin the defendants from disturbing the plaintiffs.
