ושפיכות דמים גופיה מנלן סברא הוא כי ההוא דאתא לקמיה דרבא א"ל מרי דוראי אמר לי זיל קטליה לפלני' ואי לא קטלינא לך א"ל ליקטלוך ולא תיקטול מאי חזית דדמא דידך סומק טפי דילמא דמא דההוא גברא סומק טפי
The Gemara asks: And from where do we derive this halakha with regard to murder itself? The Gemara answers: It is based on logical reasoning that one life is not preferable to another. The Gemara relates an incident to demonstrate this: This is similar to a certain man who came before Rava and said to him: A local official said to me: Go kill so-and-so, and if not I will kill you. Rava said to him: It is preferable that he should kill you and you should not kill. What did you think, that your blood is redder and more precious than his? Perhaps that man’s blood is redder. Apparently, one may not save his own life by taking someone else’s.

ור' יהושע בן קרחה נמי הכתיב את חמשת בני מיכל בת שאול אמר לך רבי יהושע וכי מיכל ילדה והלא מירב ילדה מירב ילדה ומיכל גידלה לפיכך נקראו על שמה ללמדך שכל המגדל יתום בתוך ביתו מעלה עליו הכתוב כאילו ילדו:
The Gemara asks: And according to Rabbi Yehoshua ben Korḥa as well, isn’t it written: “And the five sons of Michal, daughter of Saul, whom she bore to Adriel” (II Samuel 21:8). Rabbi Yehoshua ben Korḥa could have said to you to understand it this way: And did Michal give birth to these children? But didn’t Merab give birth to them for Adriel? Rather, Merab gave birth to them and died, and Michal raised them in her house. Therefore, the children were called by her name, to teach you that with regard to anyone who raises an orphan in his house, the verse ascribes him credit as if he gave birth to him.
