Contradiction with 1 Kings 6:7
1 Kings 6:7 specifies the construction of the temple using stones prepared at the quarry, implying no work or noise at the temple site, which contrasts with Exodus 27:8 that suggests making the altar hollow with boards where assembly and work are required on site.
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.
