'According to the Law' in the Bible

Forasmuch as thou art sent of the king, and of his seven counsellers, to inquire concerning Judah and Jerusalem, according to the law of thy God which is in thine hand;

Now therefore let us make a covenant with our God to put away all the wives, and such as are born of them, according to the counsel of my lord, and of those that tremble at the commandment of our God; and let it be done according to the law.
