I Kings 6:21-22 and 29-31

"So Solomon overlaid the inside of the temple with pure gold. He stretched gold chains across the front of the inner sanctuary, and overlaid it with gold."

"The whole temple he overlaid with gold, until he had finished all the temple; also he overlaid with gold the entire altar that was by the inner sanctuary."

"Then he carved all the walls of the temple all around, both the inner and outer sanctuaries, with carved figures of cherubim, palm trees, and open flowers."

"And the floor of the temple he overlaid with gold, both the inner and outer sanctuaries."

"For the entrance of the inner sanctuary he made doors of olive wood; the lintel and doorposts were one-fifth of the wall."

(Solomon was said to be the richest king who ever lived. And these two chapters [6-7] in I Kings really nail that point home. And there is such detail in the Word as well--how can anyone deny it's authenticity?)
