Charles Ellicott Commentary Ezra 6:5

"And also let the gold and silver vessels of the house of God, which Nebuchadnezzar took forth out of the temple which is at Jerusalem, and brought unto Babylon, be restored, and brought again unto the temple which is at Jerusalem, every one to its place; and thou shalt put them in the house of God." — Ezra 6:5 (ASV)

And also let the golden and silver vessels ... be restored. — The desecration of these vessels by Belshazzar (Daniel 5:2–3) was thus to be expiated. Every word, including the twice repeated “house of God,” is most emphatic.
