Translated from the Vilna edition.
A baraita. The year wherein Shim‘on the Righteous died, he had told them he would die that year. They asked: ‘How do you know?’ He replied to them: ‘Every Yom Kippur an elder meets me wearing white and wrapped in white. He goes in (the Holy of Holies) with me and comes out with me. This year, an elder wearing black and wrapped in black met me. He went in with me, but he did not come back out with me.’ A short time later he fell ill for seven days and then died, and his brethren priests were unable to use the Lord’s Name in blessings. At the time of his (Shim’on’s) departure, he said to them: ‘My son Khonyo (i.e., Onias) will serve (as high priest) after me.’ His brother Shim‘i was jealous of him because he was two and a half years older than him (Khonyo). He said to him: ‘Come and I will teach you the sacrificial service.’ He dressed him in a slip and tied a brassiere around him and stood him next to the altar. Then he (Shim‘i) said to his fellow priests: ‘Look at how he is fulfilling the vow which he made to his lover: (namely) “Today when I serve as high priest, I shall wear your slip and brassiere!”’ His fellow priests tried to kill him, but he ran away from them with them hot on his heels. He escaped to Alexandria in Egypt, built an altar there, and offered on it idolatrous sacrifices.
