to stand guard over someone or something the way a sentry or garrison does, whether to hold them in or to keep danger out
In everyday Greek this was a soldier's word. It is what a sentry does, or a whole garrison: to stand watch over a city, a road, or a gate. Paul uses it in its plainest sense when he recalls how a ruler in Damascus posted guards at the city gates to catch him as he tried to slip away (2 Corinthians 11:32).
The striking thing about the word is that guarding cuts two ways. The same sentry who keeps enemies out also keeps prisoners in, so the one verb can mean either "shelter" or "confine." Which one is in view depends entirely on whose side the guard is on. Greek writers had long traded on this doubleness: a person could be "under guard" as a captive or as someone under protection.
The four New Testament uses spread across this range:
- a literal watch set at the gates of Damascus to trap Paul (2 Corinthians 11:32)
- the law holding people in custody until Christ came, shut in together (συγκλείω) under its charge (Galatians 3:23)
- the peace of God standing sentry over the heart and the mind (Philippians 4:7)
- God's own power keeping believers safe until the last day (1 Peter 1:5)
In three of the four the guard is a friend, and the word becomes a promise: the believer is garrisoned, walled in by peace and by power. Only under the law does the guarding pinch, and even there scholars debate whether the law is a jailer or a protective escort. The picture never changes; only the guard does.
Nuances
Whether Paul pictures the law as a hostile jailer that imprisons, or as a protective guardian holding people in custody until Christ.
