American Standard Version (ASV):
For when by reason of the time ye ought to be teachers, ye have need again that some one teach you the rudiments of the first principles of the oracles of God; and are become such as have need of milk, and not of solid food.
King James Version (KJV):
For when for the time ye ought to be teachers, ye have need that one teach you again which [be] the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.
