John Gill Commentary 2 Kings 22:6

"unto the carpenters, and to the builders, and to the masons, and for buying timber and hewn stone to repair the house." — 2 Kings 22:6 (ASV)

Unto carpenters, and builders, and masons
Who were employed, some in mending the woodwork, and others in repairing the stone walls

and to buy timber and hewn stone to repair the house ;
not only money was to be given them for their workmanship, but to buy timber and stone to work with.
