Gittin 47A

פירקן! אמר ליה: תנן: המוכר עצמו ואת בניו לגוים ⁠– אין פודין אותו, אבל פודין את הבנים ⁠– משום קלקולא, וכל שכן הכא דאיכא קטלא.

Redeem me. R' Ami said to him: We learned in a Mishnah: With regard to one who sells himself and his children as slaves to non-Jews, he is not redeemed. However, his children are redeemed due to the harm of becoming assimilated among the non-Jews, and all the more so here, where there is a concern that leaving him in bondage may lead to his death, he should be redeemed.

אמרו ליה רבנן לרבי אמי: האי ישראל מומר הוא, דקא חזו ליה דקאכיל נבילות וטריפות! אמר להו: אימא לתיאבון הוא דקאכיל.

The rabbis said to R' Ami: This man is a Jewish apostate, as they saw him when he was eating unslaughtered animal carcasses and animals with a wound that will cause them to die within 12 months [tereifot]. He said to them: Say that he was eating them due to his appetite, not because he is an apostate, but because he was overcome by temptation.

אמרו ליה: והא זמנין דאיכא היתירא ואיסורא קמיה, ושביק היתירא ואכיל איסורא! אמר ליה: זיל, לא קא שבקי לי דאפרקינך.

They said to him: But there are times when there are permitted and forbidden foods before him, and he sets aside the permitted food and eats the forbidden food, indicating that it is not temptation alone that causes him to transgress. Once he heard this, R' Ami said to that man: Go, because they do not allow me to redeem you.

ריש לקיש זבין נפשיה ללודאי, שקל בהדיה חייתא וגלגלתא, אמר: גמירי דיומא בתרא כל דבעי מינייהו עבדי ליה, כי היכי דליחול אדמיה.

The Talmud recounts a related incident: Reish Lakish sold himself to gladiators. He took a bag and a round stone inside of it with him. He said: There is a tradition that on the final day of a captive’s life, before his captors kill him, they do for him anything that he requests of them, so that he would forgive them for the spilling of his blood.
