"The house, while it was being built, was built of stone prepared at the quarry, and there was neither hammer nor axe nor any iron tool heard in the house while it was being built." 1 Kings 6:7 NASB, bolls.life/NASB/11/6/7
"So Solomon overlaid the inside of the house with pure gold. And he drew chains of gold across the front of the inner sanctuary, and he overlaid it with gold." 1 Kings 6:21 NASB, bolls.life/NASB/11/6/21
How do "they overlaid the house within with pure gold" if "there was no hammer nor axe [nor] any tool of iron heard in the house"?
