Hebrews 5:12-14

Whiston(i) 12 For when for the time ye ought to be teachers, ye have need that one teach you again which [be] the first principles of the words of God; and are become such as have need of milk, and not of strong meat. 13 For every one that useth milk, [is] unskilful in the word of righteousness: for he is still a babe, 14 But strong meat belongeth to them that are of full age, to those who by reason of use have their senses exercised to discern both good and evil.
