_Ransom_ means something to loosen with; that is, a redemptive price.

It is the means or price or value which can be used in loosening or releasing something that is in bondage or in restraint or imprisoned.

Necessarily the ransom price must be exactly equivalent to, or corresponding with, that which justice requires of the thing or being that is in bondage or imprisonment.

Hence we say that ransom means an exact corresponding price.

A perfect man sinned and was sentenced to death; hence an exact corresponding price would be the death of another perfect man and the value of that life presented in place of the one who first sinned and was held in bondage.
[199]_Sin-offering_ means the presentation and use of the ransom-price.
On the atonement day performed by the Jews in type, the blood of the bullock represented the poured-out life; and therefore it stood for the ransom-price or value of the life.
