A Greek verb meaning to sound out loudly, to ring out, to reverberate. From ex (out) and echeo (to sound/echo). Used in 1 Thessalonians 1:8 to describe the Thessalonians' faith as having sounded forth like a trumpet throughout Macedonia and Achaia.
Paul's use of execheo for the Thessalonian church's witness is striking — their faith did not merely spread quietly but rang out like a trumpet or echo throughout the regions. Authentic faith cannot be contained; it resonates beyond its origin, reverberating in places the original believers never visited. The Thessalonians became a model (typos) for all believers in Macedonia and Achaia — their transformed lives under persecution were proclamation. The church's primary missionary instrument is not strategy but the sound of transformed lives echoing the gospel.
