'Leaders' in the Bible

We also asked them their names to make them known to you, that we might write down the {name of their leaders}.

and who extended to me loyal love before the king and his counselors, and before all of the mighty officials of the king. I took courage, for the hand of Yahweh my God was upon me, and I gathered leaders from Israel to go up with me.

Please let our leaders stand for the whole assembly, and let all that are in our cities who have married foreign women come at set times, and with them the elders of and judges of each city, until the fierce wrath of our God because of this matter is averted from us."
