Numbers 11:24

And Moses went out, and told the people the words of the LORD, and gathered the seventy men of the elders of the people, and set them round about the tabernacle.

Moses ... gathered the seventy ... and set them round about the tabernacle ... That place was chosen for the convocation, because, as it was there God manifested Himself, there His Spirit would be directly imparted-there the minds of the elders themselves would be inspired with reverential awe, and their office invested with greater respect in the eyes of the people.
