Exodus 

“If men struggle with each other and strike a woman with child so that she gives birth prematurely, yet there is no injury, he shall surely be fined as the woman’s husband may demand of him, and he shall pay as the judges decide. But if there is any further injury, then you shall appoint as a penalty life for life, eye for eye, tooth for tooth, hand for hand, foot for foot, burn for burn, wound for wound, bruise for bruise,” (Exodus 21:22-25 NASB1995).

Exodus 21:22 speaks of two men fighting. Moses explains that if the child is born “prematurely”, this is to say that the baby miscarries, yet there is no other injury, he is merely to be fined. If the man brings further injury, then punishment shall be inflicted upon him. 

A person may question why the causing of a miscarriage does not cause a greater punishment, but the context seems to make it out that this was an accidental loss in the middle of a fight. It would seem that the crime of accidental killing is differentiated from intentional murder. As Ellicott explains in his commentary, “It is assumed that this hurt would probably take place through the interference of a pregnant wife in some strife wherein her husband was engaged. It would almost certainly be accidental,” (Ellicot).

We can learn from this passage that God is just and understands that accidents happen; even so, such accidents need righteous judgment, “For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord,” (Romans 6:23 NASB1995).
