John Gill Commentary 2 Kings 12:15

"Moreover they reckoned not with the men, into whose hand they delivered the money to give to them that did the work; for they dealt faithfully." — 2 Kings 12:15 (ASV)

Moreover, they reckoned not with the men into whose hand they
delivered the money to be bestowed on the workmen
That is, the king's secretary and the high priest, or his officer, never called to account the overseers of the workmen, to whom they committed the money to pay them with; never examined how they laid it out, and for what:

for they dealt faithfully ;
they saw they acted such an honest and upright part, and such an high opinion had they of them, that they never examined their accounts, or called for their bills.
