Acts 23:13-22 - More than forty men were involved in this plot

23:13-15

There were over forty men involved in this plot, no donut encouraging one another in their evil scheme. We see a similar form of madness with Islamic terrorists (or terrorists of any sort) who think that by their atrocities they are somehow pleasing God. These plotters went to the Sanhedrin and got them involved in the plan. They would get the commander to send Paul to them, but they would capture Paul and kill him on the way.

23:16

So some men were making plots against Paul, God was not inactive. Paul's nephew learnt of the plot and went to the barracks to tell Paul. We should not fear when we learn of men making schemes. For God knows all that is happening, and He is not inactive. At present transidealogues, amongst others, make evil plans, but God will not stand by forever.

23:17-22

On learning of the plot Paul called one of the centurions and told him to take his nephew to the commander. The commander would want to be aware of the plot for two reasons. One was to avoid any trouble as far as possible, and the other was that Paul was a Roman citizen. He would be held responsible if any harm came to a Roman citizen. So the nephew was taken to the commander and informed him of the plot. The commander warned the nephew not to let anyone know that he had informed the commander. This would be both for the young man’s own safety, and so that the commander could be one step ahead of the plotters.
