'Princes' 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,

And this man shall be Peace. When the Assyrian shall come into our land, and when he shall tread in our palaces, then shall we raise against him seven shepherds, and eight princes of men.
