'Elders' in the Bible

Boaz selected ten of the town elders and spoke to them, "Sit down here." So they sat down

So I thought to myself I ought to tell you that you must make a public purchase of this before the town residents and the elders of my people. So if you intend to act as the related redeemer, then do so. But if not, let me know, because except for you and I after you there is no one to fulfill the duties of a related redeemer." The man responded, "I will act as related redeemer."

At this, Boaz addressed the elders and all of the people: "You all are witnesses today that I hereby redeem everything from Naomi that belonged to Elimelech, including what belonged to Chilion and Mahlon,

Then all of the assembled people, including the elders who were there, said, "We are witnesses! May the LORD make this woman who enters your house like Rachel and Leah, who together established the house of Israel. May you prosper in Ephrathah, and may you excel in Bethlehem!
