4 he will not falter or be discouraged till he establishes justice on earth. In his teaching the islands will put their hope."
7 Because the Sovereign Lord helps me, I will not be disgraced. Therefore have I set my face like flint, and I know I will not be put to shame.
(Read Isaiah 50:4-9)
As Jesus was God and man in one person, we find him sometimes speaking, or spoken of, as the Lord God; at other times, as man and the servant of Jehovah. He was to declare the truths which comfort the broken, contrite heart, those weary of sin, harassed with afflictions. And as the Holy Spirit was upon him, that he might speak as never man spake; so the same Divine influence daily wakened him to pray, to preach the gospel, and to receive and deliver the whole will of the Father. The Father justified the Son when he accepted the satisfaction he made for the sin of man. Christ speaks in the name of all believers. Who dares to be an enemy to those unto whom he is a Friend? or who will contend with those whom he is an Advocate? Thus St. Paul applies it, Romans 8:33.

Commentary on Isaiah 42:1-4
(Read Isaiah 42:1-4)
This prophecy was fulfilled in Christ, Matthew 12:17. Let our souls rely on him, and rejoice in him; then, for his sake, the Father will be well-pleased with us. The Holy Spirit not only came, but rested upon him, and without measure. He patiently bore the contradiction of sinners. His kingdom is spiritual; he was not to appear with earthly honours. He is tender of those oppressed with doubts and fears, as a bruised reed; those who are as smoking flax, as the wick of a lamp newly lighted, which is ready to go out again. He will not despise them, nor lay upon them more work or more suffering than they can bear. By a long course of miracles and his resurrection, he fully showed the truth of his holy religion. By the power of his gospel and grace he fixes principles in the minds of men, which tend to make them wise and just. The most distant nations wait for his law, wait for his gospel, and shall welcome it. If we would make our calling and election sure, and have the Father delight over us for good, we must behold, hear, believe in, and obey Christ.
