'Reason' in the Bible

"But you, Jeremiah, get yourself ready! Go and tell these people everything I instruct you to say. Do not be terrified of them, or I will give you good reason to be terrified of them.

So then I, the Lord who rules over all, have something to say concerning the prophets of Jerusalem: 'I will make these prophets eat the bitter food of suffering and drink the poison water of judgment. For the prophets of Jerusalem are the reason that ungodliness has spread throughout the land.'"

There is no reason why you and your people should die in war or from starvation or disease! That's what the Lord says will happen to any nation that will not be subject to the king of Babylon.
