to provide practical help to someone in need, especially material or financial support given out of one's own resources.
This is a hands-on word for meeting someone's needs, not a soft word for helping out in general. In the everyday Greek of the first century it named what a patron did for a dependent, what a family did for its widowed relatives, what a friend did for a friend in hard times: handing over real aid from what you have. Both times it appears in the New Testament it carries this weight of tangible provision.
The word grew out of an older idea of being enough for someone. Centuries earlier it could mean warding off danger, but by the first century that fighting sense had faded and the word had settled into meaning to provide for, relieve, and support. Personal letters, legal documents, and even a grave inscription from the period use it for a person's ongoing care of those who could not manage on their own.
The two New Testament uses form a matched pair. In the first, an older widow qualifies for the church's support partly because she herself once relieved people in distress. In the second, believers are told to provide for their own widowed relatives so that the church's limited funds can be reserved for widows who have no one else. The same word describes both the giving she once did and the giving now expected of her family.
Disputed
How much the prefixed epi- shapes the compound's force beyond the base verb arkeo ("to be enough, suffice"). This concerns nuance, not the core meaning.
- majorityThe prefix is directional: it focuses the sufficiency on a specific person in need, so the verb means to render assistance particularly fitted to the need.; Louw & Nida, Greek-English Lexicon of the New Testament Based on Semantic Domains, sec. 35.32; I. Howard Marshall, The Pastoral Epistles, ICC (1999); Philip H. Towner, The Letters to Timothy and Titus, NICNT (2006)
- minorityThe prefix intensifies the base verb, so the sense is to be strong enough for another's need.; J. H. Thayer, A Greek-English Lexicon of the New Testament, s.v.; G. Abbott-Smith, A Manual Greek Lexicon of the New Testament, s.v.
- minorityThe prefix adds no special force; the compound is simply the ordinary transitive verb for rendering sufficient support.; BDAG (Bauer-Danker-Arndt-Gingrich), 3rd ed., s.v.; LSJ (Liddell-Scott-Jones), s.v.
