Athrooizo appears once in the New Testament (Luke 11:29) when a crowd was gathering to Jesus. The word comes from athroos (assembled together) and describes the spontaneous assembly of people around a central figure or event. It is distinguished from more formal assembly words by its sense of a crowd gathering of its own momentum — drawn, rather than summoned.
Though appearing only once in the NT, athrooizo captures a recurring Gospel dynamic: crowds gathering around Jesus, drawn by the word of His teaching and the testimony of His miracles. Luke 11:29 notes that as the crowds gathered, Jesus began to speak — the assembly of seekers always creates an opportunity for divine teaching. The theological counterpart is Hebrews 10:25's episunagoge — the deliberate assembling of believers. Together these words frame gathering as both a Spirit-drawn impulse and a covenant discipline. The eschatological gathering of all nations before Christ (Matthew 25:32) is the ultimate athrooizo.
