https://en.wikipedia.org/wiki/High_Priest_of_Israel

The Great Sanhedrin alone had the right to appoint, or confirm the appointment of, the high priest. His consecration might take place only in the day-time. Two high priests must not be appointed together. Every high priest had a “mishneh” (a second) called the Segan, or “memunneh“, to stand at his right; another assistant was the “Catholicos“ (“Yad”, l.c. 16–17)

Israeli President Reuven Rivlin paid a visit to Pope Francis in Rome, accompanied by his personal secretary Rivkah – an Orthodox-Jewish woman. When a person usually greets the pope, they shake his hand and bow down. But when Rivkah’s turn came to greet the pope, she explained to him that for religious reasons she could not shake his hand, nor could she bow down since he was wearing a cross. The pope then covered his cross with his hand, and bowed down to her!
