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. Unto the end of the world - אל קצה הארץ el ketseh haarets - Instead of אל el, to, עד ad, Unto, is the reading of two of Kennicott's MSS.; and one of mine has מקצה mikketseh, "From the end of the earth."
Behold, thy salvation cometh "Lo, thy Savior cometh" - So all the ancient Versions render the word ישעך yishech.
Behold, his reward - See note on Isaiah 40:10, Isaiah 40:11. This reward he carries as it were in his hand. His work is before him - he perfectly knows what is to be done; and is perfectly able to do it. He will do what God should do, and what man cannot do; and men should be workers with him. Let no man fear that the promise shall not be fulfilled on account of its difficulty, its greatness, the hinderances in the way, or the unworthiness of the person to whom it is made. It is God's work; he is able to do it, and as willing as he is able.
