Ezra 6:12

And the God that hath caused His name to dwell there destroy all kings and people that shall put to their hand to alter and to destroy this house of God which is at Jerusalem, the Temple should be inviolate forever. I, Darius, have made a decree; let it be done with speed. So the formal and solemn edict went forth which protected the Jews in the building of their Temple. God has His servants also among the kings and the mighty ones of the earth, who obey Him and further the cause of His kingdom.
