The one instance where it actually makes any specific reference to abortion or causing a miscarriage in any way: Exodus 21:22
ASV: And if men strive together, and hurt a woman with child, so that her fruit depart, and yet no harm follow; he shall be surely fined, according as the woman's husband shall lay upon him; and he shall pay as the judges determine.
The Bible prescribes a monetary fine as the punishment for abortion. Which is to say, God's word is that abortion is, while not morally good, not as evil as, say, sassing back to your parents (the Biblically-mandated punishment for which is death, as per Leviticus 20:9).
