Zechariah 6:8

Then cried he upon me, and spake unto me, saying, Behold, these that go toward the north country have quieted my spirit in the north country.

The chariots sent out toward the north country have quieted the Spirit in that northern region. The vision discloses an oversight that reaches to the whole field of the work. The eyes watching over it are open to the management of every part of the cause.
