…so He will sprinkle many nations. Kings will shut their mouths because of Him, for they will see what had not been told them, and they will understand what they had not heard. (52:15; HCSB)
The servant redeemer is going to sprinkle many nations. This also seems to point to the work of the cross, as sprinkling refers to atonement that people received as the high priest sprinkled blood on the mercy seat and on the worshiper for consecration. The servant will cleanse the people. But what should be fascinating to us is that the sprinkling is upon the nations, that is, the Gentiles. The Gentiles are going to see something that had not been told to them. They are going to understand what they have not heard.
The word “sprinkle” may also mean “startle,” as your margins may indicate. This is also a fitting description. God was going to do something shocking and outstanding. Something amazing is going to happen and the nations are going to see and understand what took place. The contrast to this statement is made in verse 1 (now we can see that we are missing the context by starting the reading in the first verse of chapter 53).
