'Rod of God' in the Bible

and Moses taketh his wife, and his sons, and causeth them to ride on the ass, and turneth back to the land of Egypt, and Moses taketh the rod of God in his hand.

and Moses saith unto Joshua, 'Choose for us men, and go out, fight with Amalek: to-morrow I am standing on the top of the hill, and the rod of God in my hand.'

Their houses are peace without fear, Nor is a rod of God upon them.
