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.

Zechariah 6:1-8

Vision Eight: The Chariots

6:1 Once more I looked, and this time I saw four chariots emerging from between two mountains of bronze. 6:2 Harnessed to the first chariot were red horses, to the second black horses, 6:3 to the third white horses, and to the fourth spotted horses, all of them strong. 6:4 Then I asked the angelic messenger who was speaking with me, “What are these, sir?” 6:5 The messenger replied, “These are the four spirits of heaven that have been presenting themselves before the Lord of all the earth. 6:6 The chariot with the black horses is going to the north country and the white ones are going after them, but the spotted ones are going to the south country. 6:7 All these strong ones are scattering; they have sought permission to go and walk about over the earth.” The Lord had said, “Go! Walk about over the earth!” So they are doing so. 6:8 Then he cried out to me, “Look! The ones going to the northland have brought me peace about the northland.”
