1 Pe 2:9-10

9 But you are a chosen race, a royal priesthood, a dedicated nation, [God's] own purchased, special people, that you may set forth the wonderful deeds and display the virtues and perfections of Him Who called you out of darkness into His marvelous light. [Ex 19:5,6.]

10 Once you were not a people [at all], but now you are God's people; once you were unpitied, but now you are pitied and have received mercy. [Hos 2:23.]
