Hebrews 5:12-14

CAB(i) 12 For indeed, although you ought to be teachers by this time, again you have need for someone to teach you what are the elements of the beginning of the oracles of God; and you have come to need milk and not solid food. 13 For everyone who partakes of milk is unacquainted with the word of righteousness, for he is an infant. 14 But solid food is for the mature, for those because of their practice have their senses trained for the distinguishing of both good and evil.
