The 'eye for an eye' passage (Exodus 21:22) establishes proportional justice, not revenge, and further proves that sins are not equal in God's legal framework.

Exodus 21:22-25 describes a scenario where a pregnant woman is accidentally struck during a fight between two men. If the premature birth results in injury or death to the child, the offender receives a proportional punishment matching what was done to the child. This is courtroom justice, not personal retaliation. Jesus' later teaching on this (turning the other cheek) is about offering grace rather than demanding the justice one deserves — it does not invalidate the underlying principle that different wrongs deserve different punishments.
