Most of the discussion regarding where life begins is framed within the Old Testament. And, within that context we also find all the other teachings of God, which are relevant. Therefore we should also recognize that within the context of the "Law", this subject should never become an issue. Not because there were no
clinics, nor because they were so
enlightened, but because both the woman and fetus would be aborted - by law - along with the father.
Deut. 22
", , , , the tokens of virginity be not found for the damsel: Then they shall bring out the damsel to the door of her father's house, and the men of her city shall
stone her with stones that she die: because she hath wrought folly in Israel, to play the whore in her father's house: so shalt thou put evil away from among you.
(22)
If a man be found lying with a woman married to an husband, then t
hey shall both of them die, both the man that lay with the woman, and the woman: so shalt thou put away evil from Israel.
(23)
If a damsel that is a virgin be betrothed unto an husband, and a man find her in the city, and lie with her; Then ye shall bring them both out unto the gate of that city, and
ye shall stone them with stones that they die; the damsel, because she cried not, being in the city; and the man, because he hath humbled his neighbour's wife: so thou shalt put away evil from among you.
No questions as to whether she is pregnant, here. You may have your feelings about this, but it is very clear that the possibility of a terminated pregnancy was/is a reality.
No way to know if a woman was pregnant for quite a while, back then.
Abortion was required when chastity failed.
