ἐντρέφω
I nourish on, am educated in
Definition
The verb ἐντρέφω means 'to nourish on' or 'to be educated in.' It carries the dual sense of physical nourishment and intellectual or spiritual training. In its only New Testament occurrence (1 Timothy 4:6), it describes being 'nourished on the words of the faith,' blending the metaphor of feeding with the idea of being thoroughly instructed. This suggests a process of internalizing and being sustained by Christian teaching, not merely hearing it.
Biblical Usage
ἐντρέφω is used only once in the New Testament, in 1 Timothy 4:6. Here, Paul instructs Timothy that by pointing out certain truths to the brothers, he will be a good servant of Christ Jesus, 'being nourished on the words of the faith and of the good doctrine which you have followed.' The usage is metaphorical, applying the concept of nourishment to spiritual instruction within the pastoral context of the Pastoral Epistles.
Etymology
Derived from the preposition ἐν (en, meaning 'in') and the verb τρέφω (trephō, meaning 'to nourish,' 'feed,' or 'rear'). Literally, it means 'to nourish in' or 'to feed on.' The compound emphasizes the idea of something being taken in and internalized as sustenance, which naturally extended to education and training of the mind.
Semantic Range
This word is theologically significant as it connects spiritual growth with the metaphor of nourishment. It presents sound doctrine not as abstract information but as essential sustenance for the Christian life and ministry. Understanding this Greek term enriches the reading of 1 Timothy 4:6 by highlighting that effective service requires being continually fed by and rooted in the truths of the faith, much like a body is sustained by food.
In the ancient Greco-Roman world, education and philosophical training were often described using metaphors of nourishment and feeding. The concept of being 'nourished on' teachings would resonate as a picture of deep, formative learning that shapes one's character and life, not just the acquisition of facts.
τρέφω (trephō, G5142) — The root verb, meaning simply 'to nourish' or 'feed,' without the intensive 'in' prefix. παιδεύω (paideuō, G3811) — Means 'to train,' 'instruct,' or 'discipline,' focusing more on the educational process than the internal sustenance.
