'Heads' in the Bible

Then Solomon assembled the elders of Israel, and all the heads of the tribes, the princes of the fathers of the children of Israel, to Jerusalem, to bring up the ark of the covenant of Jehovah out of the city of David, which is Zion.

And certain of the heads of the children of Ephraim, Azariah the son of Johanan, Berechiah the son of Meshillemoth, and Hezekiah the son of Shallum, and Amasa the son of Hadlai, stood up against them that came from the war,

And king Hezekiah and the princes commanded the Levites to sing praise to Jehovah with the words of David, and of Asaph the seer. And they sang praises with gladness, and bowed their heads and worshipped.
