12 For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food.
13 For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe.
14 But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil.
1 Therefore, leaving the discussion of the elementary principles of Christ, let us go on to perfection, not laying again the foundation of repentance from dead works and of faith toward God,
2 of the doctrine of baptisms, of laying on of hands, of resurrection of the dead, and of eternal judgment.
3 And this we will do if God permits.
4 For it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit,
5 and have tasted the good word of God and the powers of the age to come,
6 if they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put Him to an open shame.
7 For the earth which drinks in the rain that often comes upon it, and bears herbs useful for those by whom it is cultivated, receives blessing from God;
8 but if it bears thorns and briars, it is rejected and near to being cursed, whose end is to be burned.
Hebrews 5:12-6:8
