'Heads' in the Bible

These [are] the ones summoned from the community, the leaders of their ancestors' tribes; they [are] the heads of Israel's clans.

the leaders of Israel, the heads of {the families}, presented an offering; they [were] the leaders of the tribes and [were] the ones in charge of the counting.

But if they blow only one, the leaders, the heads of the thousands of Israel, will assemble to you.

So Moses commanded them, Eleazar the priest, Joshua son of Nun, and the heads of the {families} of the tribes of the {Israelites}.
