In Nebuchadnezzar's dream, what was the statue's head made of?

Answer: Gold

The head was pure gold, the chest silver, the belly bronze; Daniel told the king, "You are that head of gold."

“The head of the statue was pure gold, its chest and arms were silver, its belly and thighs were bronze, Wherever the sons of men or beasts of the field or birds of the air dwell, He has given them into your hand and has made you ruler over them all. You are that head of gold.”— Daniel 2:32, 2:38 (BSB)
