3794 oxýrōma (from the root oxyroō, "fortify") – a fortified, military stronghold; a strong-walled fortress (A-S), used only in 2 Cor 10:4. Here 3794/oxýrōma ("a heavily-fortified containment") is used figuratively of a false argument in which a person seeks "shelter" ("a safe place") to escape reality.

[3794 (oxýrōma) is also used for a prison in antiquity (BAGD). "The word is not common in Classical Greek, but occurs frequently in the Apocrypha. In its use here there may lie a reminiscence of the rock-forts on the coast of Paul's native Cilicia, which were pulled down by the Romans in their attacks on the Cilician pirates. Pompey inflicted a crushing defeat upon their navy off the rocky stronghold of Coracesium on the confines of Cilicia and Pisidia" (WS, 833).]
