5 The Sovereign Lord has opened my ears; I have not been rebellious, I have not turned away.
5 The Lord GOD hath opened mine ear, and I was not rebellious, neither turned away back.
5 The Lord GOD has opened my ear, and I was not rebellious; I turned not backward.
5 The Master, God, opened my ears, and I didn't go back to sleep, didn't pull the covers back over my head.
5 The Lord God has opened My ear; And I was not rebellious, Nor did I turn away.
5 The Sovereign Lord has spoken to me, and I have listened. I have not rebelled or turned away.
6 Sacrifice and offering thou didst not desire; mine ears hast thou opened:
6 In sacrifice and offering you have not delighted, but you have given me an open ear.
6 Doing something for you, bringing something to you - that's not what you're after. Being religious, acting pious - that's not what you're asking for. You've opened my ears so I can listen.
6 Sacrifice and offering You did not desire; My ears You have opened. Burnt offering and sin offering You did not require.
6 You take no delight in sacrifices or offerings. Now that you have made me listen, I finally understand - you don't require burnt offerings or sin offerings.
(Read Psalm 40:6-10)
The psalmist foretells that work of wonder, redemption by our Lord Jesus Christ. The Substance must come, which is Christ, who must bring that glory to God, and that grace to man, which it was impossible the sacrifices should ever do. Observe the setting apart of our Lord Jesus to the work and office of Mediator. In the volume, or roll, of the book it was written of him. In the close rolls of the Divine decrees and counsel, the covenant of redemption was recorded. Also, in all the volumes of the Old Testament something was written of him, John 19:28. Now the purchase of our salvation is made, the proclamation is sent forth, calling us to come and accept it. It was preached freely and openly. Whoever undertook to preach the gospel of Christ, would be under great temptation to conceal it; but Christ, and those he calls to that work, are carried on in it. May we believe his testimony, trust his promise, and submit to his authority.
Matthew Henry's Commentary on Isaiah 50:5
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.
