John Wesley on Numbers 11:24

Moses went out - Out of the tabernacle, into which he entered to receive God's answers from the mercy - seat. The seventy men - They are called seventy from the stated number, though two of them were lacking, as the Apostles are called the twelve, Mt 26:20, when one of that number was absent. Round the tabernacle - Partly that the awe of God might be imprinted upon their hearts, that they might more seriously undertake and more faithfully manage their high employment, but principally, because that was the place where God manifested himself, and therefore there he would bestow his spirit upon them.
