“Elders” existed before the giving of the law at Sinai, and if they are not simply heads of Families then they are the products of social/cultural impotence, political bondage, and the slave mentality acquired in Egypt.

Patriarchs as "Elders"
In the New Testament, the "elder" is usually considered an exclusively "ecclesiastical" office. In the Old Testament it is usually considered a "civil" office. In both testaments they are either a temporary, pedagogical appointed office, or they are the natural patriarchal heads. (Of course there is no such thing as "natural"; a Godly patriarch is a gift of God's grace.) The goal is the unification of "civil" and "ecclesiastical" functions in the family, if they are legitimate functions at all.
