Zechariah 6:1-3

1Now again I looked up, and four chariots were coming out from between two mountains; and the mountains were mountains of [firm, immovable] bronze (divine judgment).

2The first chariot had red horses (war, bloodshed), the second chariot had black horses (famine, death),

3the third chariot had white horses (victory), and the fourth chariot had strong dappled horses (death through judgment).
