Makkot מכות

Three subjects, a chapter each: witnesses convicted of falsehood—they are done to as they meant to have done to the accused; the accidental killer fleeing to a city of refuge; and the offences punished by lashes.

Here too is the best-known line about capital punishment: a Sanhedrin that puts a man to death once in seven years is called destructive, and Rabbi Tarfon and Rabbi Akiva say that had they sat on the Sanhedrin no one would ever have been executed. The tractate ends with the sages weeping at the sight of a fox coming out of the Holy of Holies, while Rabbi Akiva laughed: the prophecy of destruction has come true—so will the prophecy of consolation.

Order: Nezikin. There is Gemara in both the Babylonian and the Jerusalem Talmud.
