In the article referenced by PaladinGirl it refers to Exodus 21:22-25. The article says that this passage shows that God does not give equal moral worth to the woman as to a fetus. The article correctly says that the passage states that when a woman is injured the one who injured her were pay by eye for eye, tooth for a tooth, life for a life. The article incorrectly says that the passage states that a killed fetus in only punishable by a fine and thence a fetus is not a full human being since the punishment for killing it is less than the punishment for killing a human. But read the passage for yourself.
Exodus 21:22-25
22: If men strive, and hurt a woman with child, so that her fruit depart from her, and yet no mischief follow: he shall be surely punished, according as the woman's husband will lay upon him; and he shall pay as the judges determine.
23: And if any mischief follow, then thou shalt give life for life,
24: Eye for eye, tooth for tooth, hand for hand, foot for foot,
25: Burning for burning, wound for wound, stripe for stripe.
The passage does not say the man will merely have to pay a fine for killing the child in the womb, it says he will be punished according as the womans husband will lay upon him and that he will also pay as the judges determine (wow, double punishment, once from the husband and again from the judges). There are no limitations in that sentence, the husband can punish the man in any way, any way includes life in prison (or more likely slavery back then since they didnt have nomadic prisons) or death or whatever else he sees fit. Then when the husband is done with him its time for the judges to determine another punishment for him.
Based on this passage it sure seems like God holds a child in the womb in very high regard.
