Zechariah 6:5-8

5And the angel answered and said to me, "These are going out to the four winds of heaven, after presenting themselves before the Lord of all the earth.

6The chariot with the black horses goes toward the north country, the white ones go after them, and the dappled ones go toward the south country."

7When the strong horses came out, they were impatient to go and patrol the earth. And he said, "Go, patrol the earth." So they patrolled the earth.

8Then he cried to me, "Behold, those who go toward the north country have set my Spirit at rest in the north country."
