'Rod of God' in the Bible

And Moses took his wife and his sons, and set them upon an ass, and he returned to the land of Egypt: and Moses took the rod of God in his hand.

And Moses said unto Joshua, Choose us out men, and go out, fight with Amalek: to morrow I will stand on the top of the hill with the rod of God in mine hand.

Their houses are safe from fear, neither is the rod of God upon them.

I am the man who has seen afflictionunder the rod of God’s wrath.
