'Heads' in the Bible

In a circle around the throne were twenty-four other thrones, and seated on those thrones were twenty-four elders. They were dressed in white clothing and had golden crowns on their heads.

Now the locusts looked like horses equipped for battle. On their heads were something like crowns similar to gold, and their faces looked like men's faces.

Now this is what the horses and their riders looked like in my vision: The riders had breastplates that were fiery red, dark blue, and sulfurous yellow in color. The heads of the horses looked like lions' heads, and fire, smoke, and sulfur came out of their mouths.

For the power of the horses resides in their mouths and in their tails, because their tails are like snakes, having heads that inflict injuries.

Then another sign appeared in heaven: a huge red dragon that had seven heads and ten horns, and on its heads were seven diadem crowns.

Then I saw a beast coming up out of the sea. It had ten horns and seven heads, and on its horns were ten diadem crowns, and on its heads a blasphemous name.

One of the beast's heads appeared to have been killed, but the lethal wound had been healed. And the whole world followed the beast in amazement;

So he carried me away in the Spirit to a wilderness, and there I saw a woman sitting on a scarlet beast that was full of blasphemous names and had seven heads and ten horns.

But the angel said to me, "Why are you astounded? I will interpret for you the mystery of the woman and of the beast with the seven heads and ten horns that carries her.

(This requires a mind that has wisdom.) The seven heads are seven mountains the woman sits on. They are also seven kings:

And they threw dust on their heads and were shouting with weeping and mourning, "Woe, Woe, O great city -- in which all those who had ships on the sea got rich from her wealth -- because in a single hour she has been destroyed!"
