Other than the countless scriptures on taking innnocent life, we have this passage from the Epistle of Barnabus
Cold Steel, you are correct that their are many scriptures that warn about taking an innocent life. But your argument is flawed because you assume that just because a woman is pregnant, that fertilized egg cell within her is a human life. The Bible never states that to be the case. In other words, not even God believes that.
There are many arguments that could be made here, but the simpliest is this: True life does not require a host. If it requires being attached to the mother in order to live, such as an embryo, than it is not yet a life on its own. It is still the mother's life that sustains it, and thus a part of her body.
Remember, a female human is born with 1-2 million egg cells, with about 300,000 of them still available at puberty. Of those, only about 400 are released during her reproductive life. Even then, she may only give birth to a fraction of that number, if she has children at all. If there is a God, he would know that a woman would never use all the egg cells he put in her, much like he would know that men would never utilize the billions of sperm cells their bodies produce. Putting an egg cell and a sperm cell together does not in itself make a human life. It has to grow and transform into one, and then be able to survive on its own. Since the Bible is completely silent on this aspect, it is inappropriate and sacriligious to use it to support the anti-abortion movement.
As Paul wrote at 1 Cor. 4:6: "Do not go beyond what is written."
