Ezra 5:5

But the eye of their God was upon the elders of the Jews, who might naturally have been overawed by the coming of these high officials and been inclined to give up their project in sheer terror, that they could not cause them to cease till the matter came to Darius, the Jews were permitted to go on with their work until the king himself had handed down a decision in the matter; and then they, the investigators, returned answer by letter concerning this matter. Because the Jews had informed Tatnai that they were acting by permission and upon a decree issued by Cyrus himself, the viceroy thought best to refer the case to the king for adjustment. God Himself holds His sheltering hand over the work done in His honor, and therefore it can never fail.
