There is no mention of abortion in the Bible, but there are many biblical passages and principles that we should take into account.
13 For you created my inmost being;
you knit me together in my mother’s womb.
14 I praise you because I am fearfully and wonderfully made;
your works are wonderful,
I know that full well.
15 My frame was not hidden from you
when I was made in the secret place,
when I was woven together in the depths of the earth.
16 Your eyes saw my unformed body;
all the days ordained for me were written in your book
before one of them came to be.
22 “Now suppose two men are fighting, and in the process they accidentally strike a pregnant woman so she gives birth prematurely. If no further injury results, the man who struck the woman must pay the amount of compensation the woman’s husband demands and the judges approve. 23 But if there is further injury, the punishment must match the injury: a life for a life, 24 an eye for an eye, a tooth for a tooth, a hand for a hand, a foot for a foot, 25 a burn for a burn, a wound for a wound, a bruise for a bruise.
