Kolose 1:26-27

1:26 that is, the mystery that has been kept hidden from ages and generations, but has now been revealed to his saints. 1:27 God wanted to make known to them the glorious ¹  riches of this mystery among the Gentiles, which is Christ in you, the hope of glory.

[1:27]  ¹ tn The genitive noun τῆς δόξης (ths doxhs) is an attributive genitive and has therefore been translated as “glorious riches.”
