'Rod' in the Bible

What will ye? shall I come unto you with a rod, or in love and a spirit of gentleness?

having a golden altar of incense, and the ark of the covenant overlaid round about with gold, wherein was a golden pot holding the manna, and Aaron's rod that budded, and the tables of the covenant;

and he shall rule them with a rod of iron, as the vessels of the potter are broken to shivers; as I also have received of my Father:

And there was given me a reed like unto a rod: and one said, Rise, and measure the temple of God, and the altar, and them that worship therein.

And she was delivered of a son, a man child, who is to rule all the nations with a rod of iron: and her child was caught up unto God, and unto his throne.

And out of his mouth proceedeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness of the wrath of God, the Almighty.
