Isaiah 42:18 Meaning: Can the Deaf Really Hear?

Two Hebrew words carry the sting of this verse. Cheresh (deaf) and ivver (blind) usually describe physical conditions, but here they are painted over a spiritual reality: people who have ears but will not hear, eyes but will not see. The prophet is not talking about a disability; he is talking about a choice.

The verbs deepen the challenge. Shama (hear) often means more than sound entering the ear, it means to listen with the intent to obey. And nabat (look) paired with ra’ah (see) pictures someone deliberately turning their gaze in order to perceive what is really there. The command does not mock human limitation. It confronts a willful refusal to pay attention. God is saying: You have the capacity. Now use it.

Christians have read this verse in several ways, all pointing to the same tension. Many commentators, from Matthew Henry to the Cambridge Bible, see the primary address as Israel itself, the people who were called to be God’s servant but had become dull and disobedient. John Calvin agreed but added that the indictment stretches to all people, because everyone has enough evidence of God to be held responsible. Others, like the Baptist scholar John Gill, read it as an appeal to the Gentiles, who were spiritually deaf and blind apart from the Gospel. What unites these views is the recognition that the command is not cruel but merciful: it calls people to wake up and receive the light that is already shining.

Some readers think the verse is absurd, how can a deaf person hear, or a blind person see? The mistake is taking the terms literally when the context shows they are figurative. In fact, the people addressed are morally and spiritually dull, not physically impaired. God is not asking the impossible; He is exposing their stubborn refusal to listen and look. The command is a loving jolt, not a logical contradiction.

Here is a question to sit with this week: Where am I not listening? It might be a quiet inner resistance to something God has been saying through Scripture, through a friend, or through circumstances. The verse calls us to stop pretending we cannot hear. Take one area where you have felt a nudge and ignored it. Then do something concrete, open that passage again, have that hard conversation, or simply say to God, “I have been deaf to You here. Give me ears to hear.” The hope is that the same God who commands also enables. He does not mock our blindness; He leads the blind by a way they do not know.
