'Heads' in the Bible

Shave your heads bald as you mourn for the children you love; shave your foreheads as bald as an eagle, for they are taken from you into exile.

And I said, Hear, I pray you, O heads of Jacob, and ye princes of the house of Israel; Is it not for you to know judgment?

Therefore night will fall, and you will receive no visions; it will grow dark, and you will no longer be able to read the omens. The sun will set on these prophets, and the daylight will turn to darkness over their heads.

Hear this, I pray you, ye heads of the house of Jacob, and princes of the house of Israel, that abhor judgment, and pervert all equity.

The heads thereof judge for reward, and the priests thereof teach for hire, and the prophets thereof divine for money: yet will they lean upon the LORD, and say, Is not the LORD among us? none evil can come upon us.
