In Exodus 16, the Israelites grumbled about not having enough food, so the Lord said to Moses "I will rain down bread" . Moses reminded the people that it was God who delivered them in Egypt and that in the morning the glory of the Lord would again be seen and He would provide for their needs. God gave them instructions , testing their obedience, in regard to the gathering of food each day. They were to gather twice as much on the sixth day, since there would be none available to gather on the seventh day. Also, they were told not to keep any for the next day, except for on the sixth day. The Lord also provided meat each evening, sending quail to them each day at twilight. Some of the people wend out to gather on the seventh day, so the Lord said to Moses "How long will you refuse to keep my commands and my instructions?"
