'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 to 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 my hand.

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