(1) Whenever a person kills a human being, he transgresses a negative commandment, as it says, "Do not murder." (Exodus 20:13)...
(5) When a murderer kills willfully, he should not be killed by witnesses or observers until he is brought to court and sentenced to death...
(6) When does the above apply? When the person has already transgressed and performed the transgression for which he is liable to be executed by the court. When, however, a person is pursuing a colleague with the intention of killing him - even if the pursuer is a minor - every Jewish person is commanded to attempt to save the person being pursued, even if it is necessary to kill the pursuer.
(7) What is implied? If the rodef (pursuer) was warned and continues to pursue his intended victim, even though he did not acknowledge the warning since he continues his pursuit he should be killed. If it is possible to save the pursued by damaging one of the limbs of the rodef, one should. Thus, if one can strike him with an arrow, a stone or a sword, and cut off his hand, break his leg, blind him or in another way prevent him from achieving his objective, one should do so. If there is no way to be precise in one's aim and save the person being pursued without killing the rodef, one should kill him, even though he has not yet killed his victim...

(22) When men fight, and one of them pushes a pregnant woman and a miscarriage results, but no other damage ensues, the one responsible shall be fined according as the woman’s husband may exact from him, the payment to be based on reckoning. (23) But if other damage ensues, the penalty shall be life for life, (24) eye for eye, tooth for tooth, hand for hand, foot for foot, (25) burn for burn, wound for wound, bruise for bruise.
(ו) הָאִשָּׁה שֶׁהִיא מַקְשָׁה לֵילֵד, מְחַתְּכִין אֶת הַוָּלָד בְּמֵעֶיהָ וּמוֹצִיאִין אוֹתוֹ אֵבָרִים אֵבָרִים, מִפְּנֵי שֶׁחַיֶּיהָ קוֹדְמִין לְחַיָּיו. יָצָא רֻבּוֹ, אֵין נוֹגְעִין בּוֹ, שֶׁאֵין דּוֹחִין נֶפֶשׁ מִפְּנֵי נָפֶשׁ:
(6) If a woman is having trouble giving birth, they cut up the child in her womb and bring it forth limb by limb, because her life comes before the life of the child. But if the greater part has come out, one may not touch it, for one may not set aside one person's life for that of another.
והתניא בת כהן שנישאת לישראל ומת טובלת ואוכלת בתרומה לערב אמר רב חסדא טובלת ואוכלת עד ארבעים דאי לא מיעברא הא לא מיעברא ואי מיעברא עד ארבעים מיא בעלמא היא
In the case of the daughter of a priest who married an Israelite and her husband died on that same day, she immerses to purify herself, as she is ritually impure due to their intercourse, and she may partake of teruma that same evening. Evidently, the Sages were not concerned that she became pregnant from the initial act of intercourse, even that of marriage. Rav Ḥisda said: She immerses and partakes of teruma only until forty days after her husband’s death, when there is still no reason for concern, as if she is not pregnant then she is not pregnant. And if she is pregnant, until forty days from conception the fetus is merely water. It is not yet considered a living being, and therefore it does not disqualify its mother from partaking of teruma.

(1) He who wounds his fellow is liable to compensate him on five counts: for injury, for pain, for healing, for loss of income and for indignity. ‘For injury’: How so? If he blinded his fellow’s eye, cut off his hand or broke his foot, [his fellow] is looked upon as if he was a slave to be sold in the market and they assess how much he was worth and how much he is worth. ‘For pain’? If he burned him with a spit or a nail, even though it was on his fingernail, a place where it leaves no wound, they estimate how much money such a man would be willing to take to suffer so...
MISHNA: In the case of a pregnant woman who is taken by the court to be executed, the court does not wait to execute her until she gives birth. Rather, she is killed immediately. But with regard to a woman taken to be executed who sat on the travailing chair [hamashber] in the throes of labor, the court waits to execute her until she gives birth. GEMARA: Isn’t it obvious that the court executes the pregnant woman rather than waiting? After all, it is part of her body. The Gemara answers: It was necessary for the mishna to teach this, as it might enter your mind to say that since it is written: “And if men strive together, and hurt a woman with child, so that her offspring depart…he shall be fined, as the woman’s husband shall place upon him” (Exodus 21:22), the fetus is considered to be the property of the husband. If so, the court should wait until she gives birth before executing her, and not cause him to lose the fetus. Consequently, the mishna teaches us that the court does not take this factor into account.
Tzitz Eliezer 9:51 Chap. 3
If there is a danger to the mother from continuing the pregnancy, one should permit abortion without hesitation. Also, if her health is poor and to cure her or to relieve her from great pain it is necessary to abort the fetus, even if she is not in actual danger, there is room to permit it, based on the halachic authority’s evaluation of the situation.
§ The Sages taught: There are three partners in the creation of a person: The Holy One, Blessed be He, and his father, and his mother. His father emits the white seed, from which the following body parts are formed: The bones, the sinews, the nails, the brain that is in its head, and the white of the eye. His mother emits red seed, from which are formed the skin, the flesh, the hair, and the black of the eye. And the Holy One, Blessed be He, inserts into him a spirit, a soul, his countenance [ukelaster], eyesight, hearing of the ear, the capability of speech of the mouth, the capability of walking with the legs, understanding, and wisdom. And when a person’s time to depart from the world arrives, the Holy One, Blessed be He, retrieves His part, and He leaves the part of the person’s father and mother before them.
