ἐξαρτίζω

From the study of 2 Timothy 3:17

Range of meaning

'To fit out completely, equip, furnish', and also 'to complete, finish' a period of time. The ex- prefix makes it stronger: fully, thoroughly. Here it appears as a perfect passive participle, which describes a lasting state: having been equipped and remaining so.

Against the English

KJV 'throughly furnished' is accurate. 'Throughly' is the old spelling of 'thoroughly', and 'furnished' meant 'supplied with what is needed', as a house is furnished. BSB 'fully equipped' and WEB 'thoroughly equipped' keep the force of the prefix. ESV and NASB drop it ('equipped'). YLT ('having been completed') takes the 'complete' sense of the verb.

Used elsewhere in the period

Its only other NT use is Acts 21:5, 'when our days there were completed'. Moulton & Milligan cite documentary papyri that use it for property let out fully equipped, for example an oil-press leased with all its fittings. Josephus also uses it for equipping. It belonged to everyday practical language, not to religious vocabulary.

From the study of Acts 21:5

Range of meaning

(1) To equip fully, fit out, furnish. It was used of fitting out ships, armies and households. (2) To bring something to completion, to finish. It is used of work, and here of a stretch of time.

Against the English

English versions all treat it as 'when the days were over' (KJV 'accomplished those days'). This is right for the sense here. The verb's other meaning, 'thoroughly equipped', is the one in 2 Timothy 3:17, its only other New Testament use.

Used elsewhere in the period

BDAG gives 'to finish, complete' for Acts 21:5. Moulton–Milligan list papyrus examples where the verb means finishing a job or a set period, so this was ordinary everyday Greek, not a Lukan oddity. The 'equip' sense is common in Hellenistic writers, including the fitting out of ships.
