Hebrews 5:12-14

ACV(i) 12 For also men who ought to be teachers because of the time, ye have need again for some man to teach you the rudiments of the beginning of the oracles of God, and have become men who have need of milk, and not of solid food. 13 For every man partaking of milk is unskilled in the word of righteousness, for he is childlike. 14 But solid food is for mature men, those having their sensibilities trained through practice for the discernment of both good and evil.
