Daniel 2:32-33
2:32 As for that statue, its head was of fine gold, its chest and arms were of silver, its belly and thighs were of bronze.
2:33 Its legs were of iron; its feet were partly of iron and partly of clay.
Daniel 2:37-40
Daniel Interprets Nebuchadnezzar’s Dream
2:37 “You, O king, are the king of kings. The God of heaven has granted you sovereignty, power, strength, and honor.
2:38 Wherever human beings, wild animals, and birds of the sky live – he has given them into your power. He has given you authority over them all. You are the head of gold.
2:39 Now after you another kingdom will arise, one inferior to yours. Then a third kingdom, one of bronze, will rule in all the earth.
2:40 Then there will be a fourth kingdom, one strong like iron. Just like iron breaks in pieces and shatters everything, and as iron breaks in pieces all of these metals, so it will break in pieces and crush the others.
