'Food' in the Bible

For although by this time you should be teachers, you again need to have someone teach you the rudiments of the first principles of the oracles of God. You have come to need milk, and not solid food.

But solid food is for those who are full grown, who by reason of use have their senses exercised to discern good and evil.

Don't be carried away by various and strange teachings, for it is good that the heart be established by grace, not by food, through which those who were so occupied were not benefited.
