Zechariah 6:5-8

5The angel answered me, “These are the four spirits of the heavens, which go out after presenting themselves before the Lord of all the earth,

6with the chariot with the black horses going toward the north country; then the one with the white horses follows after them [because there are two northern powers to overcome], and the chariot with the dappled horses goes toward the south country.”

7When the strong horses went out, they were eager to patrol the earth. And the Lord said, “Go, patrol the earth.” So they patrolled the earth [watching and protecting it].

8Then He called out to me and said to me, “See, those who are going to the north country have quieted My Spirit [of wrath] in the north country.”
