Charles Ellicott Commentary Exodus 16:19

"And Moses said unto them, Let no man leave of it till the morning." — Exodus 16:19 (ASV)

Let no man leave of it.—Moses must have been divinely instructed to issue this command. It was doubtless given in order that the Israelites might realise their absolute dependence upon God for food from day to day, and might thus be habituated to complete trust and confidence in Him.
