I wonder if they're still fasting and refusing to eat anything?
You know who I'm talking about, right? The 40+ Jews who bound themselves under a horrific curse (or oath) that they would not eat or drink until they had killed Paul. They conspired with the chief priest and his cronies to have Paul brought down from the garrison under the pretense of "just asking a few more questions." (Acts 23)
The problem with their plan? God always has the right people in the right place at the right time. Paul's nephew became aware of the plot, and he came and told Paul who then referred him to the leader of the garrison. Paul was sent out of Jerusalem the same night under cover of darkness and with the protection of almost 500 Roman soldiers (including horsemen).
That's why you should never fear the threats and plans of the wicked against you as a child of God. Can they do bad things? Certainly. That's part of wicked people having a will and a choice. Do they get to call all the shots for a child of God living in the will of God? Absolutely not.
Never forget this simple truth: "God rules in the affairs of men."
(See Dan 4:17)
So, what happened to them? Are they still fasting? Did they starve themselves to death in adherence to their oath? Or did they admit defeat and break their fast with a plate of crow? I suspect hunger overtook their devotion.
