I believe that would be one of the Ten Commandments #5 if your Catholic ,#6 if your Protestant.
Exodus 20: 13 "You shall not murder.
As the early Christian writer Tertullian pointed out, the law of Moses ordered strict penalties for causing an abortion. We read, “If men who are fighting hit a pregnant woman and she gives birth prematurely [Hebrew: “so that her child comes out”], but there is no serious injury, the offender must be fined whatever the woman’s husband demands and the court allows. But if there is serious injury, you are to take life for life, eye for eye, tooth for tooth, hand for hand, foot for foot” (Ex. 21:22–24).
The Didache
“The second commandment of the teaching: You shall not murder. You shall not commit adultery. You shall not seduce boys. You shall not commit fornication. You shall not steal. You shall not practice magic. You shall not use potions. You shall not procure [an] abortion, nor destroy a newborn child” (Didache 2:1–2 [A.D. 70]).
Jerome
“I cannot bring myself to speak of the many virgins who daily fall and are lost to the bosom of the Church, their mother. . . . Some go so far as to take potions, that they may insure barrenness, and thus murder human beings almost before their conception. Some, when they find themselves with child through their sin, use drugs to procure abortion, and when, as often happens, they die with their offspring, they enter the lower world laden with the guilt not only of adultery against Christ but also of suicide and child murder” (Letters 22:13 [A.D. 396]).
