John Wesley on Isaiah 50:4

Given 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.
