v1-4: Contrasting with idols, "my servant," Jesus Christ; chosen by God, dependent upon God, accepted by God, anointed by God; meek and humble, gentle and compassionate, faithful and persevering. See 52.13-53.12; Luke 4.18-19; Phil 2.7; Heb 4.15. The words here are quoted in Matt 12.18-21.
Commentators have identified the 'Servant Songs;' 42.1-9; 49.1-6; 50.4-9; 52.13-53.12.
The bruised reed would be about to break, the smoking flax about to be extinguished; but the servant of the Lord brings strength and light. Men would cast out a bruised reed as useless, but the Lord Jesus would not break it, but strengthen it. Men would reject the smoking flax, but the Lord will breathe on it, and make it shine even brighter. Yet He is more than just a comfort to the weak, but persevering to bring in "justice on earth." Through Him the islands, Gentiles, will find hope.
'There is a great want about all Christians who have not suffered. Some flowers must be broken, or bruised before they emit any fragrance. All the wounds of Christ send out sweetness - all the sorrows of Christians do the same. Commend me to a bruised brother, a broken reed - one like him the Son of Man. The Son of Man is never far from him.' (Mr Purves, of Jedburgh (19th century), quoted by Andrew Bonar in Robert Murray M'Cheyne.)
v5: God the Lord, speaking with authority. See also Amos 4.13; the creator of all things; inanimate creation, and also living, breathing people.
v6-7: The Servant of God comes first to Jew, then to Gentile. Christ is truly the light to all the world. This light opens the eyes of the blind, both physically and spiritually. He releases those imprisoned (Luke 4.18), in the snare of the enemy, in the snare of legalism, of false religion.
v8: God is unique, and intolerant of those who claim His throne. Yet He has given His glory to Jesus Christ, His Son, the Servant of God. He displayed the glory of the Godhead.
v9: New things declared before they happened, as in 41.27. The prophet warns the people that God is about to do something new and different. He describes the Servant of God, the Messiah, through these 'songs.' Through the coming of Christ, these 'new things' are made known.
v10-13: People throughout the earth will be led to praise God. The light of God would no longer be restricted to one small nation.
v14-17: The Lord had delayed His judgment, through His longsuffering. Israel, having trusted in idols, would be ashamed and repentant, and would be restored.
v18-19: The Servant's secret, He is deaf and blind, not influenced by the world around Him, only listening to the voice of God. The world brings tempting sights and sounds, and the Servant rejects them.
v20: The image of the Servant's deafness and blindness is used to expose the spiritual deafness and blindness of the people; those who claimed to be wise were actually ignorant, John 9.41.
v21: The Lord God will honour His law, even though the people rejected it. See Rom 3.31; under Christ, the law's true meaning is revealed.
v22: Those who disobeyed suffered loss.
v23-25: Israel had been ignorant of the course of the judgments he suffered. "Was it not the Lord?" We must learn our lessons.
