Hebrews 5:12-14

ABU(i) 12 For though ye ought, on account of the time, to be teachers, ye again have need that some one teach you the first principles of the oracles of God, and are become such as have need of milk, and not of solid food. 13 For every one who partakes of milk is inexperienced in the word of righteousness; for he is a child. 14 But solid food belongs to those who are of full age, who by use have their senses exercised to discern good and evil.
