I think I see where the confusion is; there seems to be two quite different wordings of
the same verse with regards to the condition of the child after the woman is hit/hurt:
Exodus 21:22 in the NIV: "If people are fighting and hit a pregnant woman and she
gives birth prematurely but there is no serious injury, the offender must be fined
whatever the woman's husband demands and the court allows."
Exodus 21:22 in the CJB: "If people are fighting with each other and happen to hurt a
pregnant woman so badly that her unborn child dies, then, even if no other harm
follows, he must be fined. He must pay the amount set by the woman's husband and
confirmed by judges."
One mentions no serious injury, the other mentions the baby outright dying.
Isn't relying on ancient texts fun?
