Hebrews 5:12-13
Hebrews 5:12-13 ASV
For when by reason of the time ye ought to be teachers, ye have need again that some one teach you the rudiments of the first principles of the oracles of God; and are become such as have need of milk, and not of solid food. For every one that partaketh of milk is without experience of the word of righteousness; for he is a babe.
