4 The Lord God has given me the tongue of those who are experienced, so that I may be able to give the word a special sense for the feeble: every morning my ear is open to his teaching, like those who are experienced: 5 And I have not put myself against him, or let my heart be turned back from him. 6 I was offering my back to those who gave me blows, and my face to those who were pulling out my hair: I did not keep my face covered from marks of shame. 7 For the Lord God is my helper; I will not be put to shame: so I have made my face like a rock, and I am certain that he will give me my right. 8 He who takes up my cause is near; who will go to law with me? let us come together before the judge: who is against me? let him come near to me. 9 See, the Lord God is my helper; who will give a decision against me? truly, all of them will become old like a robe; they will be food for the worm.

Commentary on Isaiah 50:4-9
(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.
