'Elders' in the Bible

So all the elders of Israel came to the king at Hebron, and David made a covenant with them in Hebron before the Lord; and they anointed David king over Israel, according to the word of the Lord through Samuel.

So it was David, with the elders of Israel and the captains over thousands, who went to bring up the ark of the covenant of the Lord from the house of Obed-edom with joy.

Then David lifted up his eyes and saw the angel of the Lord standing between earth and heaven, with his drawn sword in his hand stretched out over Jerusalem. Then David and the elders, covered with sackcloth, fell on their faces.
