We read today af a JW meeting, acts 12:23 that says about Herod:
and at that moment the angel of the Lord struck him down, because he had not given the glory to God. He was eaten away by worms and died.” Acts 12:23
Herod died 4BCE in Jericho after a long life with Depression and Paranoia.
I wanted to know more sbout Herods death. I found that he may have suffered arteriosclerosis together with a deterioration of the heart and the kidneys. With that condition “Bodily poisons wouldn’t be excreted properly and would accumulate in the blood, causing general itching, sharp, constant abdominal pain, diarrhea, and possible ulceration of the bowels. In extreme cases, which is plainly what we’re dealing with here, the scrotum could become distended and gangrenous, at which point a lesion might well become infested with maggots, personal hygiene not being a priority back then.” source: http://www.straightdope.com/columns/read/196/what-loathsome-disease-did-king-herod-die-of/
I am very doubtful that God caused this death. Luke who wrote the acts most probably not knowing about Herods illness and its causes, took the opportunity to add a divine cause to scare the readers with the Old Testament “Eye to eye” God.
Threatening with such a God was the strategy of the church for Centuries despite Jesus teached about a loving and forgiving God.
