'Heads' in the Bible

And I said, Give ear, now, you heads of Jacob and rulers of the people of Israel: is it not for you to have knowledge of what is right?

Then give ear to this, you heads of the children of Jacob, you rulers of the children of Israel, hating what is right, twisting what is straight.

Its heads take rewards for judging, and the priests take payment for teaching, and the prophets get silver for reading the future: but still, supporting themselves on the Lord, they say, Is not the Lord among us? no evil will overtake us.
