'Commandment' in the Bible

The elders of the Jews built and prospered, through the prophesying of Haggai the prophet and Zechariah the son of Iddo. They built and finished it, according to the commandment of the God of Israel, and according to the decree of Cyrus, and Darius, and Artaxerxes king of Persia.

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 who tremble at the commandment of our God. Let it be done according to the law.
