'Elders' in the Bible

So all the elders of Israel came to the king at Hebron, and David made a covenant (solemn agreement) with them there before the Lord; and they anointed him king over Israel, in accordance with the word of the Lord through Samuel.

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

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