If a pregnant woman smelled [food or drink and requested it] they feed her until she recovers. A sick person —- they feed him according to [the advice of] experts, but if no experts are present, they feed him relying on his own opinion until he says, “Enough.”

If one was seized with bulmos, they feed him even forbidden foods until his vision is restored.  If one was bitten by a mad dog, they may not feed him its liver lobe. But R' Masya ben Charash permits [it].  R' Masya ben Charash also said: If one has an ailment in his throat they [may] drop medicine into his mouth on the Sabbath, because there may be a danger to life, and every possible danger to life supersedes the Sabbath.

If a building collapsed on someone [on the Sabbath, and] it is uncertain whether he is there or not, [or] it is uncertain whether he is alive or dead, [or] it is uncertain whether he is a heathen or a Jew, they [must] clear the heap [of debris] for him. If they found him alive, they [must] clear [the rest of the debris] for him, but if he is dead they leave him [there].

A sin offering and a guilt offering for a definite sin provide atonement. Death or Yom Kippur provide atonement together with repentance.  [However] repentance [alone] atones for lesser transgressions: for positive commandments and negative commandments. But for the graver [sins], it suspends [punishment] until Yom Kippur comes and provides atonement.
