72 Chambers

72 chambers
According to the record in the Talmud,

'King Ptolemy once gathered 72 Elders. He placed them in 72 chambers, each of them in a separate one, without revealing to them why they were summoned. He entered each one's room and said: 'Write for me the Torah of Moshe, your teacher.' God put it in the heart of each one to translate identically as all the others did'[8]
