Hebrew 3

Speaking to fellow Hebrews or those that are priesthood leaders in Israel, Paul taught -

"But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin."  (Hebrews 3:13)

"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.
13 For every one that useth milk is unskilful in the word of righteousness: for he is a babe.
14 But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil."  (Hebrews 5:12–14)

I see this as an obligation of modern day Elders with their families and ministering to their neighbors.
