'Elders' in the Bible

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

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

And David lifted up his eyes, and saw the angel of Jehovah standing between earth and heaven, having a drawn sword in his hand stretched out over Jerusalem. Then David and the elders, clothed in sackcloth, fell upon their faces.
