Explanatory Notes on the Whole Bible, by John Wesley, [1754-65], at sacred-texts.com
isa 50:1Thus saith the Lord - The scope of this and the next chapter, is to vindicate God's justice and to convince the Jews that they were the causes of their own calamities. Behold - You can blame none but yourselves and your own sins, for all your captivities and miseries.
isa 50:2Wherefore - The general accusation delivered in the last words he now proves by particular instances. When - When I, first by my prophets, came to call them to repentance. No man - That complied with my call. To answer - To come at my call. Is my hand - What is the reason of this contempt? Is it because you think I am either unwilling or unable to save you? A wilderness - As dry and fit for travelling as a wilderness.
isa 50:3I clothe - When it is necessary to save my people, I cover them with thick and dark clouds black as sackcloth, Rev 6:12.
isa 50:4Given me - This and the following passages may be in some sort understood of the prophet Isaiah, but they are far more evidently and eminently verified in Christ, and indeed seem to be meant directly of him. The tongue - All ability of speaking plainly, and convincingly, and persuasively. Weary - Burdened with the sense of his, deplorable condition. Wakeneth - Me, from time to time, and continually. To hear - He by his Divine power assists me to the practice of all his commands and my duties, with all attention and diligence.
isa 50:6I gave - I patiently yielded up myself to those who smote me.
isa 50:8Justifieth - God will clear up my righteousness, and shew by many and mighty signs and wonders, that I lived and died his faithful servant. Let him come - l am conscious of mine own innocency, and I know that God will give sentence for me.
isa 50:9They - Mine accusers and enemies. The moth - Shall be cut off and consumed by a secret curse.
isa 50:10The voice - Of Christ, who is called God's servant, by way of eminency and to intimate that though he was God, yet he would take upon himself the form of a servant. In darkness - Not in sin, but in misery, that lives in a disconsolate and calamitous condition. No light - No comfort. Trust - Let him fix his faith and hope in the mercy, and faithfulness, of the Lord, declared in his word, and in his interest in God, who by the mediation of this servant is reconciled to him and made his God.
isa 50:11All ye - You that reject the light which God hath set up, and seek for comfort and safety, by your own inventions. Walk - Use your utmost endeavours to get comfort from these devices. This - This shall be the fruit of all, you shall receive nothing but vexation and misery.
