Semitic society (Jews, Arabs, etc.) is organized in tribes. One is not "elected" by a "committee". An elder from one family would not in any way rule over another man's family. Each family was represented in public life by the alpha male of their clan. The alpha male was by default the eldest male but if that's not an option it could be another. Respect for one's elders was crucial to an orderly society. Notice that even Egypt was organized with elders:
Gen_50:7 And Joseph went up to bury his father: and with him went up
all the servants of Pharaoh, the elders of his house, and all the
elders of the land of Egypt,
Conspicuously absent from Paul's list of offices (which were temporary) is "elder":
Eph 4:11 And it is he who gifted some to be apostles, others to be
prophets, others to be evangelists, and still others to be pastors and
teachers, Eph 4:12 to equip the saints, to do the work of ministry,
and to build up the body of the Messiah Eph 4:13 until all of us are
united in the faith and in the full knowledge of God's Son, and until
we attain mature adulthood and the full standard of development in the
Messiah. Eph 4:14 Then we will no longer be little children, tossed
like waves and blown about by every wind of doctrine, by people's
trickery, or by clever strategies that would lead us astray.
So Peter knows nothing of the "Elders" in modern Churches who act as a board of directors over all of the families of the assemblies. Presbyterian style "Board of Elders" has more in common with a Roman Senate than with the thousands of years of Semitic representation by the alpha male of the family.
My primary source for my observation is the scriptures themselves. The last mention of elders in the scriptures prior to the NT is 3 Maccabees 1:25:
3Ma_1:25 The elders who surrounded the king strove in many ways to
divert his haughty mind from the design which he had formed.
Obviously these are not Presbyterians but rather Jews interacting with the king.
Joseph, War, mentions the elders as well:
And when he was at Antioch, he wrote to him, and commanded him to come
to him quickly to Ptolemais: upon which Jonathan did not intermit the
siege of the citadel, but took with him the elders of the people,
and the priests, and carried with him gold, and silver, and garments,
and a great number of presents of friendship, and came to Demetrius,
and presented him with them, and thereby pacified the king's anger.
