Acts 19:34
But when they knew that he was a Jew, all with one voice about the space of two hours cried out, Great is Diana of the Ephesians.
Cross-references
Acts 19:26 reports Demetrius' claim that Paul threatens Artemis worship—this directly provokes the crowd's two‑hour chant in v34.
Acts 19:28 records the first shout 'Great is Artemis'; v34 shows they continued shouting the same phrase for two hours when they saw Alexander.
In Acts 19:24, Demetrius the silversmith incites the riot—his livelihood from Artemis idols leads to the crowd's outcry here.
In 1 Kings 18:26, Baal's prophets cry out for hours with no answer—parallel to the Ephesians shouting 'Great is Artemis' for two hours. Both are futile pagan appeals.
Matthew 6:7 condemns vain repetitions like the heathen use—the Ephesians' two‑hour chant is a perfect example of the practice Jesus warns against.
In 2 Timothy 4:14, Alexander the coppersmith is mentioned—possibly the same Alexander put forward in Acts 19:33 during this riot.
Revelation 13:4 shows people worshiping the beast with acclamations—similar to the Ephesians' cry 'Great is Artemis.' Both are idolatrous shouts to false gods.
