Beautiful chapter! Isaiah says He will not rest until Israel is blessed at long last.
V.2-4 We sometimes hold up a special treasure for everyone to see. This is what the Lord is going to do with Israel in the “day of the Lord.” (See “E” to “F” on your chart).
V.5-12 God’s promise to Israel.
V.10-12 Always remember that the great blessing into which Israel is going to be brought during the millennium all depends on what the Lord Jesus has done on the cross for them. The unbelieving nation is now relying entirely on their own vaunted strength of their army and not on the Lord at all. All these shall be swept away and a nation of believers in the Lord will emerge. So here we read “behold thy salvation cometh.” The Lord Jesus is their salvation (and ours).
