Pro lifers, like most hardline religious people are cherry pickers. Which, granted, isn't hard to do with a book that flip flops more than Mitt Romney, and does a near complete one eighty on most subjects between part one and part two.
Actually, there are several lines in the bible that specifically state that life begins at the first breath:
Genesis 2:7: He “breathed into his nostrils the breath of life and it was then that the man became a living being”. Although the man was fully formed by God in all respects, he was not a living being until after taking his first breath.
Job 33:4 : “The spirit of God has made me, and the breath of the Almighty gives me life.”
Ezekiel 37:5&6: “Thus says the Lord God to these bones: Behold, I will cause breath to enter you, and you shall live. And I will lay sinews upon you, and will cause flesh to come upon you, and cover you with skin, and put breath in you, and you shall live; and you shall know that I am the Lord.”
And then there's the one that clearly states abortion isn't murder.
Exodus 21:22-25: “If men strive and hurt a woman with child, so that her fruit depart from her, and yet no misfortune follow, he shall be surely punished according as the woman’s husband will lay upon him; and he shall pay as the judges determine.And if any misfortune follow, then thou shalt give life for life, And if any misfortune follow, then thou shalt give life for life, eye for eye, tooth for tooth, hand for hand, foot for foot, burning for burning, wound for wound, stripe for stripe."
This clearly reads that the fruit departing from her is no misfortune upon itself. Simple and clear cut. if the bible is the word of god, then god thinks that destroying the fruit of a woman's womb does not equate to murder.
