500. Verse 9 And Enosh lived ninety years; and he beget Kenan.

As has been stated, 'Enosh' means a third Church, even less celestial than the Church of Seth, but nevertheless one of the Most Ancient Churches. 'Kenan' means a fourth Church which came after the previous ones.

'Kenan' or 'Cainan' signifies the fourth church after Enos.
