The First Principles of the Oracles of God

It may be of some surprise (it was to me) that the phrase “first principles” is used only once in scripture.

(Heb. 5:12)  "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."

A similar phrase starts the next chapter accompanied by a list of six foundation principles.
