'Elders' in the Bible

Therefore came all the elders of Israel to the king to 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 by Samuel.

So David, and the elders of Israel, and the captains over thousands, went to bring up the ark of the covenant of the LORD out of the house of Obededom with joy.

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