Hebrews 5:12-14 TLV
For although you ought to be teachers by this time, again you need someone to teach you the basics of God’s sayings. You have come to need milk, not solid food.
For anyone living on milk is inexperienced with the teaching about righteousness—he is an infant.
But solid food is for the mature, who through practice have their senses trained to discern both good and evil.
TLV: Tree of Life Version
