'Elders' in the Bible

He took ten men of the elders of the city, and said, "Sit down here." They sat down.

I thought to disclose it to you, saying, 'Buy it before those who sit here, and before the elders of my people.' If you will redeem it, redeem it; but if you will not redeem it, then tell me, that I may know. For there is no one to redeem it besides you; and I am after you." He said, "I will redeem it."

Boaz said to the elders, and to all the people, "You are witnesses this day, that I have bought all that was Elimelech's, and all that was Chilion's and Mahlon's, from the hand of Naomi.

All the people who were in the gate, and the elders, said, "We are witnesses. May Yahweh make the woman who has come into your house like Rachel and like Leah, which two built the house of Israel; and treat you worthily in Ephrathah, and be famous in Bethlehem.
