John Wesley on Isaiah 52:15

So - His exaltation shall be answerable to his humiliation. Sprinkle - With his word or doctrine; which being often compared to rain or water, may be said to be sprinkled, as it is said to be dropped, Deut 32:2 Ezek 20:46. Kings - Shall be silent before him out of profound humility, reverence, and admiration of his wisdom. For - They shall hear from his mouth many excellent doctrines, which will be new and strange to them. And particularly that comfortable doctrine of the salvation of the Gentiles, which was not only new to them, but strange and incredible to the Jews themselves.
