'Elders of Israel' in the Bible

Then Joshua tore his clothes and fell to the earth on his face before the ark of the Lord until the evening, both he and the elders of Israel; and they put dust on their heads.

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

Then Joshua gathered all the tribes of Israel to Shechem, and called for the elders of Israel and for their heads and their judges and their officers; and they presented themselves before God.
