Numbers 1:4

These were the renowned of the congregation, princes of the tribes of their fathers, heads of thousands in Israel.

And Moses chose able men out of all Israel, and made them heads over the people, rulers of thousands, rulers of hundreds, rulers of fifties, and rulers of tens.

And thou shalt write Aaron’s name upon the rod of Levi: for one rod shall be for the head of the house of their fathers.

And with him ten princes, of each chief house a prince throughout all the tribes of Israel; and each one was an head of the house of their fathers among the thousands of Israel.

Moreover thou shalt provide out of all the people able men, such as fear God, men of truth, hating covetousness; and place such over them, to be rulers of thousands, and rulers of hundreds, rulers of fifties, and rulers of tens:

So I took the chief of your tribes, wise men, and known, and made them heads over you, captains over thousands, and captains over hundreds, and captains over fifties, and captains over tens, and officers among your tribes.

Now the name of the Israelite that was slain, even that was slain with the Midianitish woman, was Zimri, the son of Salu, a prince of a chief house among the Simeonites.

And the LORD said unto Moses, Take all the heads of the people, and hang them up before the LORD against the sun, that the fierce anger of the LORD may be turned away from Israel.
