Isaiah 59:21

21. As for me… saith the Lord Of late the prophet has been, but now Jehovah reappears as, the speaker; probably because he personates the “Redeemer” of the preceding verse.

This is my covenant Namely, the covenant of the Gospel, with all its spiritual benefits, which is to run on till the world ends.

My Spirit… upon thee First, on Messiah without measure; (John 3:36;) then, on his people, the devoted ones of Israel, the true Israel, they of the “west” and they of regions where is “the rising of the sun.” From these, that is, the true Israel, (Isaiah 49:3,)

“righteousness will now overflow to the whole people.” They will be raised to their high calling as God’s royal priesthood; and the oath to Abraham and the truth to Jacob will be fulfilled through successive generations, as it had been sworn to the fathers from the days of old. ( Birks.)
