John Gill Commentary Ezra 8:29

"Watch ye, and keep them, until ye weigh them before the chiefs of the priests and the Levites, and the princes of the fathers` [houses] of Israel, at Jerusalem, in the chambers of the house of Jehovah." — Ezra 8:29 (ASV)

Watch you, and keep them
The vessels, the gold, and the silver, that they be not hurt and diminished:

until you weigh them before the chief of the priests and the Levites,
and chief of the fathers of Israel at Jerusalem, in the chambers of
the house of the Lord :
that is, until they had delivered them in full weight, as they had received them, in the presence of those persons as witnesses, and into their hands, in order to be laid up in the chambers and treasuries of the temple.
