Ezra 5:17
Now therefore, if it seem good to the king, let there be search made in the king’s treasure house, which is there at Babylon, whether it be so, that a decree was made of Cyrus the king to build this house of God at Jerusalem, and let the king send his pleasure to us concerning this matter.
The verse records a request that the king have a search made in the royal archives or treasury house at Babylon to verify whether Cyrus the king had made a decree to build the temple or house of God at Jerusalem, and that he send his pleasure and decision concerning the matter. The weight of testimony holds this to have been the request of the provincial officers, while those who held it to be the Jews' request understood it as their appeal in the same terms. The search confirmed the decree, enabling Darius to authorize and support the work, with the request thus directing the Persian officials to verify the original authorization and helping to bring the matter before Darius for settlement.
