'Heads' in the Bible

And the captains, the chiefs, and the rulers, and the king's wise men who had come together, saw these men, over whose bodies the fire had no power, and not a hair of their heads was burned, and their coats were not changed, and there was no smell of fire about them.

After this I saw another beast, like a leopard, which had on its back four wings like those of a bird; and the beast had four heads, and the power of a ruler was given to it.
