Hebrews 5:12-14

BBE(i) 12 And though by this time it would be right for you to be teachers, you still have need of someone to give you teaching about the first simple rules of God's revelation; you have become like babies who have need of milk, and not of solid food. 13 For everyone who takes milk is without experience of the word of righteousness: he is a child. 14 But solid food is for men of full growth, even for those whose senses are trained by use to see what is good and what is evil.
