Zeev I am unfamiliar with rabbinical law as you have described. My Christian faith has taught me life begins at conception.I think the question of when human life begins is all of the above , a religious,legal,and medical question depending on who your speaking with and what context it is in.Focussing just on the religious does the Jewish faith teach life does not begin until actual physical birth and this coincides with the beginning of ones soul? Teachings of other faiths is fascinating to me, I appreciate the sharing of your faith. I have included a couple of vs: from the Old Testament,what does does rabbinical law teach about
Jeremiah 1:5
"Before I formed you in the womb I knew you,And before you were born I consecrated you"
and Ps. 140:13,16
For you formed my inward parts,you wove me in my mothers womb,I will give thanks to you,for I am fearfully,and wonderfully made;wonderful are your works,and my soul knows it very well.My frame was not hidden from you,when I was made in secret,and skillfully wrought in the depths of the earth;your eyes have seen my unformed substance ;and in your book were all written the days that were ordained for me,when as yet there were not one of them.
