Hebrews 5:9-12

9and having been perfected, became to all them that obey him, author of eternal salvation;

10addressed by 1God [as] high priest according to the order of Melchisedec.

11Concerning whom we have much to say, and hard to be interpreted in speaking [of it], since ye are become dull in hearing.

12For when for the time ye ought to be teachers, ye have again need that [one] should teach you what [are] the elements of the beginning of the oracles of 2God, and are become such as have need of milk, [and] not of solid food.
