'Heads' in the Bible

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

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 do they lean upon Jehovah, and say, Is not Jehovah in the midst of us? no evil shall come upon us.
