'Elders' in the Bible

Hear this, O elders, and give ear, all the inhabitants of the land. Has this happened in your days? Or the days of your ancestors?

Solemnize a fast! Call an assembly! Gather [the] elders, all [of] the inhabitants of the land [in] the house of Yahweh your God, and cry out to Yahweh.

gather [the] people, consecrate [the] assembly; assemble [the] elders, gather [the] children, even those [who are] breast-feeding; let [the] bridegroom come out from his private room, and [the] bride from her canopy.

And it will happen afterward thus: I will pour out my Spirit on all flesh, and your sons and your daughters will prophesy, and your elders will dream dreams; your young men shall see visions.
