John Gill Commentary Numbers 16:43

"And Moses and Aaron came to the front of the tent of meeting." — Numbers 16:43 (ASV)

And Moses and Aaron came before the tabernacle of the
congregation .
] Whose tent was not far from it, about which the people of Israel were gathered; and from whence they came to the tabernacle, both for shelter and safety, and for advice and instruction how to behave in this crisis; they did not go into it, but stood before it; the Lord being in the cloud over it, they stood in the door of it, (Numbers 16:50) ; so the Targum of Jonathan, "and Moses and Aaron came from the congregation to the door of the tabernacle."
