Charles Ellicott Commentary Isaiah 42:18

"Hear, ye deaf; and look, ye blind, that ye may see." — Isaiah 42:18 (ASV)

Hear, ye deaf ... — The words form the beginning of a new section. The prophet feels or sees that the great argument has not carried conviction as it ought to have done. The people to whom Jehovah speaks through him are still spiritually blind and deaf, and that people is ideally the servant of the Lord (Isaiah 41:8), in whom the pattern of the personal servant ought to have been reproduced. (Compare to John 9:39-41.)
