1 Chronicles 23:2

And Joshua called for all Israel, and for their elders, and for their heads, and for their judges, and for their officers, and said unto them, I am old and stricken in age:

And Joshua gathered all the tribes of Israel to 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.

And David consulted with the captains of thousands and hundreds, and with every leader.

And David assembled all the princes of Israel, the princes of the tribes, and the captains of the companies that ministered to the king by course, and the captains over the thousands, and captains over the hundreds, and the stewards over all the substance and possession of the king, and of his sons, with the officers, and with the mighty men, and with all the valiant men, unto Jerusalem.

Then the king sent and gathered together all the elders of Judah and Jerusalem.
