Exodus 16
3 Ref And the children of Israel said to them, It would have been better for the Lord to have put us to death in the land of Egypt, where we were seated by the flesh-pots and had bread enough for our needs; for you have taken us out to this waste of sand, to put all this people to death through need of food.
4 Ref Then the Lord said to Moses, See, I will send down bread from heaven for you; and the people will go out every day and get enough for the day's needs; so that I may put them to the test to see if they will keep my laws or not.
5 Ref And on the sixth day they are to make ready what they get in, and it will be twice as much as they get on the other days.
6 Ref And Moses and Aaron said to all the children of Israel, This evening it will be clear to you that it is the Lord who has taken you out of the land of Egypt:
7 Ref And in the morning you will see the glory of the Lord; for your angry words against the Lord have come to his ears: and what are we that you are crying out against us?
