Hebrews 5:12–14

12 For though 1by this time you ought to be teachers, you have need again for someone to teach you athe 2belementary principles of the coracles of God, and you have come to need dmilk and not solid food.

13 For everyone who partakes only of milk is not accustomed to the word of righteousness, for he is an ainfant.

14 But solid food is for athe mature, who because of practice have their senses btrained to cdiscern good and evil.
