Hear, ye deaf; and look, ye blind, that ye may see.
Hear, ye deaf - namely, to the voice of God.
Look, ye blind - to your duty and interest; willfully so (Isaiah 42:20.) In this they differ from "the blind" (Isaiah 42:16). The Jews are referred to. He had said, God would destroy the pagan idolatry. Here He remembers that even Israel, His "servant" (Isaiah 42:19), from whom better things might have been expected, is tainted with this sin.
