Mga Sanggunian sa Mishnah para sa Exodo 21:20: Mishnah Zavim & Mishnah Sanhedrin

One who had [a discharge of] semen does not defile due to zivah for a period of twenty-four hours. Rabbi Yose says: [only] that day. A non-Jew who had a discharge of semen and then converted, he immediately becomes unclean due to zivah. [A woman] who had [an issue] of blood, or had experienced difficulty [in childbirth], [the time prescribed] is twenty-four hours. One who strikes his slave, the "day or two" is twenty-four hours. A dog that eats a corpse's flesh, for three days from one time of day to the same time of day, it is considered to be in its natural state.

Slaying by the sword was performed thus: they would cut off his head by the sword, as is done by the civil authorities. R. Judah says: “This is a disgrace! Rather his head was laid on a block and severed with an axe. They said to him: “No death is more disgraceful than this.” Strangulation was performed thus: the condemned man was lowered into dung up to his armpits, then a hard cloth was placed within a soft one, wound round his neck, and the two ends pulled in opposite directions until he was dead.
