'Add' in the Bible

You must not add anything to what I command you or take anything away from it, so that you may keep the commands of the Lord your God I am giving you.

You must be careful to do everything I command you; do not add anything to it or take anything away from it.

provided you keep every one of these commands I am giving you today and follow them, loving the Lord your God and walking in His ways at all times—you are to add three more cities to these three.
