Eight of them, to wit, 72 counsellors, 72 pupils, 72 races of men, 72 languages, the languages in his school, 72 peoples whose were those languages, and the races, 72 artificers to work at it, 72 building materials including lime, bitumen, earth, and cement in equal layers, 72 paces in width, as he said:
The number of the chosen Tower
Of Nimrod, it was a shelter to men,
Four and seventy paces,
Five paces, and five thousand.
Two and seventy counsellors,
They took companies on an expedition,
Two and seventy languages
God gave to confound them.
