'Center' in the Bible

I looked and there was a whirlwind coming from the north, a great cloud with fire flashing back and forth and brilliant light all around it. In the center of the fire, there was a gleam like amber.

One third you shall burn in the fire at the center of the city, when the days of the siege are completed. Then you shall take one third and strike it with the sword all around the city, and one third you shall scatter to the wind; and I will unsheathe a sword behind them.

“This is what the Lord God says: I have set this Jerusalem in the center of the nations, with countries all around her.

Therefore this is what the Lord GOD says, "Because all of you have become dross, watch out! I'm going to gather all of you at the center of Jerusalem,

just like a smelter gathers all the silver, bronze, lead, and tin to the center of a furnace and injects fire in order to melt it, I'm going to gather you in my anger and rage, make you settle down and then I'm going to melt you down.

like melting silver at the center of a furnace. When you've been melted from the center out, then you'll know that I am the LORD. I'll pour out my anger on you.'"

in order to seize spoil and carry off plunder, to turn your hand against ruins now inhabited and against a people gathered from the nations, who have been acquiring cattle and possessions and who live at the center of the world.’
