Behold, the LORD hath proclaimed unto the end of the world, Say ye to the daughter of Zion, Behold, thy salvation cometh; behold, his reward is with him, and his work before him.
Say ye to the daughter of Zion, Behold, thy salvation cometh - embodied in the Saviour (see Zechariah 9:9).
Behold, his reward is with him, and his work (rather, His recompence for work, Isaiah 40:10 ) before him.
