Contradiction with 1 Kings 6:7
This verse states that the stones were made ready before being brought to the temple, so no tools of iron were used at the building site, contradicting any implication that making heavy stone foundations on site in 1 Kings 7:10 involved iron tools.
1 Kings 6:7: And the house, when it was in building, was built of stone made ready before it was brought thither: so that there was neither hammer nor axe [nor] any tool of iron heard in the house, while it was in building.
Contradiction with 1 Chronicles 22:2
This verse details the preparation of materials by David, which might suggest a different sourcing and preparation process than the setting of large costly stones mentioned directly in 1 Kings 7:10.
1 Chronicles 22:2: And David commanded to gather together the strangers that [were] in the land of Israel; and he set masons to hew wrought stones to build the house of God.
