Танах к Кохелет 12:8

The words of [reproof of] Koheleth [(Solomon, who gathered [kihel] many wisdoms)], the son of David, who reigned in Jerusalem [(the city of wisdom)].

The vanity (1) of the vanities (2) [of the seven days of creation (Seven "vanities" are intimated in this verse)], said Koheleth — the vanity (1) of the vanities (2) [is that] all is vanity (1, all together 7).
