In depth
From the study of Revelation 18:2
- Range of meaning
(1) guarding, keeping watch; (2) a guard or guard-post; (3) a prison or place of confinement; (4) a watch of the night. In the New Testament it overwhelmingly means 'prison' (e.g. Revelation 2:10; 20:7; 1 Peter 3:19).
- Against the English
'Hold' (KJV, YLT), 'cage' (KJV, for the birds), 'prison' (WEB, NASB), 'haunt' (BSB, ESV, NIV). 'Haunt' reads the word as 'the place they keep to'. 'Prison' keeps its usual meaning of confinement. Both are defensible; neither covers every sense of the word.
- Used elsewhere in the period
In Revelation 20:7 Satan is released 'from his prison' (the same word). Lexicons (e.g. BDAG) record a sense 'haunt, place of refuge' that some apply here. The repeated φυλακή may stand in for several different Hebrew words for 'den' and 'dwelling' found in Isaiah 13 and 34 and Jeremiah 50–51.
- Range of meaning
Guarding or a watch; a guard post or body of guards; a period of the night watch; a place of custody or prison.
- Against the English
'Prison' is the right English word, but modern prisons chiefly hold people serving sentences. Ancient custody mostly held people awaiting a decision, trial, or execution.
- Used elsewhere in the period
Luke uses the word for places of custody repeatedly in Acts (5:19; 12:5; 16:23). In this same chapter it also means a guard post (12:10, 'the first and second guard'). Rapske's study of custody in Acts describes conditions in the Roman-period world.
From the study of 2 Corinthians 6:5
- Range of meaning
From phylassō, "to guard." The word can mean the act of guarding, a guard post, a watch of the night (Matt 14:25), or the place where people are held, a prison. The plural here means separate spells of imprisonment.
- Against the English
"Imprisonments" is accurate. In the Roman world, though, prison was mostly custody while awaiting trial or punishment, not a sentence of years. Prisoners often depended on friends to bring them food.
- Used elsewhere in the period
Acts 16:23–24 (Philippi, feet in the stocks). 2 Cor 11:23 says "in prisons far more." Around AD 96, 1 Clement 5:6 remembers Paul as having "worn chains seven times." Scholars often suggest an imprisonment at Ephesus before this letter, based on 1:8–10 and 1 Cor 15:32, though Acts does not record one.
