Ochyrōma (G3794) means a stronghold, fortification, or fortress — a place of entrenched, defended power. In its one New Testament appearance (2 Corinthians 10:4), Paul uses it metaphorically for the entrenched thought systems and arguments that oppose the knowledge of God.
Paul declares that the weapons of our spiritual warfare have divine power to demolish strongholds (ochyrōmata). These are not geographic fortresses but ideological and spiritual fortifications — self-justifying arguments, proud philosophies, ingrained patterns of thought that resist God's truth. Prayer, the word, and the Spirit are the weapons. The gospel dismantles every intellectual, spiritual, and cultural stronghold that exalts itself against the knowledge of God.
