Hebrews 5:13
King James Version
“For every one that useth milk unskilful in the word of righteousness: for he is a babe.”
Context
10Called of God an high priest after the order of Melchisedec.
11Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing.
12For when for the time ye ought to be teachers, ye have need that one teach you again which the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.
13For every one that useth milk unskilful in the word of righteousness: for he is a babe.
14But strong meat belongeth to them that are of full age, those who by reason of use have their senses exercised to discern both good and evil.
