'Leaders' in the Bible

So I took the heads of your tribes, wise and experienced men, and appointed them heads over you, leaders of thousands and of hundreds, of fifties and of tens, and officers for your tribes.

‘I will make My arrows drunk with blood,And My sword will devour flesh,With the blood of the slain and the captives,From the long-haired leaders of the enemy.’

“Then he provided the first part for himself,For there the ruler’s portion was reserved;And he came with the leaders of the people;He executed the justice of the Lord,And His ordinances with Israel.”
