'According to the Law' in the Bible

Forasmuch as you are sent by the king and his seven counselors to inquire concerning Judah and Jerusalem according to the law of your God which is in your hand,

So now let us make a covenant with our God to put away all the wives and their children, according to the counsel of my lord and of those who tremble at the commandment of our God; and let it be done according to the law.
