John Gill Commentary Exodus 16:9

"And Moses said unto Aaron, Say unto all the congregation of the children of Israel, Come near before Jehovah; for he hath heard your murmurings." — Exodus 16:9 (ASV)

And Moses spoke unto Aaron Who was his prophet and spokesman to the people: say unto all the congregation of the children of Israel ; to the heads of them, to as many as could conveniently hear him, and were to report what he said to the rest:

come near before the Lord ; who was in the pillar of cloud, which from the first appearance of it never removed from them, nor the Lord from that; though some have thought, that before the tabernacle was built, there was some small tent or little tabernacle where the Shechinah was; but for this there is no foundation, there is for the other suggested:

for he has heard your murmurings ; which is repeated again and again, to observe to them the evil of it, and what notice the Lord took of it, though he indulged them in so gracious a manner he did.
