I kill ... I wound ... I will make mine arrows drunk with blood, and my sword shall devour flesh. Deuteronomy 32:39-42
Well, there's not much to say about this one. It all happens in a single verse.
Then spake Elisha unto the woman, whose son he had restored to life, saying, Arise, and go thou and thine household, and sojourn wheresoever thou canst sojourn: for the LORD hath called for a famine; and it shall also come upon the land seven years. 2 Kings 8:1
God called for a seven year famine. The Bible doesn't say why God did this.
But I guess God can starve people to death if he wants to, for any reason, or for no reason at all.
The Bible doesn't say how many God starved to death in the seven year famine, so I'll just guess 7000, 1000 per year.
