Halakhah zu Dewarim 22:24

The commandment upon the court to stone the one liable: That the court is obligated to pelt with stones one who has transgressed some sins. And one of them is one who has sexual relations with an engaged maiden, as it states (Deuteronomy 22:24), "and you shall stone them with stones." And this is one of the four well-known death penalties of the court - and they are stoning, burning, killing (beheading) and strangulation. And in Sanhedrin 49b in the chapter [entitled] Arba Mitot, Rabbi Shimon and 'our rabbis' disagreed [regarding] which is more severe, stoning or burning. And it is 'our rabbis' that said that stoning is more severe. And the matter of stoning is thus (see Mishneh Torah, The Sanhedrin and the Penalties within their Jurisdiction 15:1): Four ells distant from the house of stoning, we remove the clothes of the man who is obligated in stoning, until he remains naked, and [then] we cover his nakedness in front of him. And a woman is not stoned naked but rather with one garment. And the house of stoning was two stories tall. And he goes up there - [as do] his witnesses - and his hands are tied. And one of the witnesses pushes him on his midriff and he falls to the ground on his heart. And if he does not die from the pushing, the witnesses pick up a stone that was laying there - [weighing] a load for two people - and they release their hands and hurl the stone on his heart. And if he [still] doesn't die, his stoning is by all of Israel, as it states (Deuteronomy 17:7), "The hand of the witnesses shall be upon him first, etc."
