Zechariah 6:6-7

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.

tn The present translation takes אֲמֻצִּים (’amutsim, “strong”) to be a descriptive of all the horses – white, black, red, and spotted (cf. NAB, NIV, NLT).
