Isaiah 42:18-25
Spiritual blindness invites covenant discipline.
Scripture Text
42:18 “Hear, You deaf, and look, You blind, that You may see.
42:19 Who is blind, but my servant? Or who is as deaf as my messenger whom I send? Who is as blind as He who is at peace, and as blind as Yahweh’s servant?
42:20 You see many things, but don’t observe. His ears are open, but He doesn’t listen.
42:21 It pleased Yahweh, for His righteousness’ sake, to magnify the law and make it honorable.
42:22 But this is a robbed and plundered people. All of them are snared in holes, and they are hidden in prisons. They have become captives, and no one delivers, and a plunder, and no one says, ‘Restore them!’
42:23 Who is there among You who will give ear to this? Who will listen and hear for the time to come?
42:24 Who gave Jacob as plunder, and Israel to the robbers? Didn’t Yahweh, He against whom we have sinned? For they would not walk in His ways, and they disobeyed His law.
42:25 Therefore He poured the fierceness of His anger on Him, and the strength of battle. It set Him on fire all around, but He didn’t know. It burned Him, but He didn’t take it to heart.”

To confront Israel’s spiritual blindness and explain their suffering as covenant consequence under the Lord’s righteous judgment. Though called as the Lord’s servant, Israel is blind and deaf to God’s revelation, and their suffering results from persistent covenant disobedience.
- 42:1-4 The Lord’s chosen, Spirit-filled Servant gently and faithfully brings justice to the nations.
- 42:5-9 The Creator calls the Servant as covenant, light, opener of blind eyes, and liberator of prisoners.
- 42:10-13 The whole earth is called to sing a new song because the Lord comes as warrior.
- 42:14-17 The Lord breaks silence, judges, leads the blind, turns darkness to light, and shames idol-trusters.
- 42:18-21 Israel, the Lord’s servant and messenger, is exposed as blind and deaf.
- 42:22-25 Israel’s plunder and captivity result from sin, disobedience, and refusal to take judgment to heart.
Isaiah 42 moves from the Lord presenting His chosen Servant who will bring justice to the nations with gentleness and faithfulness, to the Lord commissioning Him as covenant and light, to a new song of worldwide praise for the Lord’s coming victory, to the Lord declaring that He will act after long restraint, to His promise to lead the blind by ways they have not known, and finally to the indictment of Israel as a blind and deaf servant who has suffered judgment but has not taken it to heart.
The chapter argues that the Lord’s mission for justice, light, covenant restoration, and liberation will be accomplished through His chosen Servant, not through blind and deaf Israel in its present condition.
