A Ransom

[ESVi] Ex. 30:12 “When you take the census of the people of Israel, then each shall give a ransom for his life to the LORD when you number them, that there be no plague among them when you number them.

A ransom is to be paid for those numbered with the Lord. It is the same for every man, rich or poor. It is the rescue and atonement for our sins.
This is what Jesus did for all those that would be numbered with Him. He did what we cannot do.
