Charles Ellicott Commentary Exodus 16:22

"And it came to pass, that on the sixth day they gathered twice as much bread, two omers for each one: and all the rulers of the congregation came and told Moses." — Exodus 16:22 (ASV)

On the sixth day they gathered twice as much.—See the third Note on Exodus 16:5.

The rulers ... came and told Moses. —They were evidently surprised, and came to Moses for an explanation. Either he had not communicated to them the Divine announcement of Exodus 16:5, or they had failed to comprehend it.
