'Elders of Israel' in the Bible

Then Joshua rent his clothes and fell upon his face to the earth before the ark of Yahweh until the evening, he and the elders of Israel, - and they lifted up dust upon their heads.

And Joshua rose up early in the morning, and mustered the people, - and went up - he and the elders of Israel, before the people, to Ai.

And Joshua gathered together all the tribes of Israel, unto Shechem, - and called for the elders of Israel, and for their heads, and for their judges, and for their officers, and they presented themselves before God.
