'Elders' in the Bible

Hear this, O elders,And listen, all inhabitants of the land.Has anything like this happened in your daysOr in your fathers’ days?

Consecrate a fast,Proclaim a solemn assembly;Gather the eldersAnd all the inhabitants of the landTo the house of the Lord your God,And cry out to the Lord.

Gather the people, sanctify the congregation,Assemble the elders,Gather the children and the nursing infants.Let the bridegroom come out of his roomAnd the bride out of her bridal chamber.
