Ezra (2 Esdras) 6:4

"And [let there be] three strong layers of stone, and one layer of timber; and the expense shall be paid out of the house of the king."
Would Cyrus give funds from the Persian treasury to rebuild the Temple?

Would Cyrus give funds from the Persian treasury to rebuild the Temple? Yes -- it was Persian policy to help restore sanctuaries in the Empire. Cyrus also repaired temples at Uruk and Ur; Darius and Cambyses each gave funds to restore a temple in Egypt. A charter decree from a Persian satrap on behalf of a local cult, paralleling this decree, was found at Xanthos in Turkey, dated to 358 BC; the text is in Greek, Lycian, and Aramaic, and it records amount of sacrifices, names of priests, the responsibility of the upkeep of the cult is specified, and the gods which are invoked to curse those who dismiss the decree are local deities.
