Tractate Yoma ("The Day") covers the Yom Kippur (Day of Atonement) ritual — the high priest's entry into the Holy of Holies, the two-goat ceremony, and the confession of Israel's sins. It is the tractate most directly concerned with how atonement works.
The Talmud was compiled by rabbis who rejected Jesus as Messiah. Yet across multiple tractates it preserves traditions that, taken together, constitute a hostile-witness confirmation of the gospel: a dying Messiah, a God who does not distinguish Jew from Gentile, a second enthroned figure beside God, an atonement sign that permanently stopped working in 30 CE, a messianic era the rabbis placed in the first century by their own arithmetic, and a prophetic era they declared closed after Malachi.
