Exodus 16:3-7

16:3 The Israelites said to them, “If only we had died by the hand of the Lord in the land of Egypt, when we sat by the pots of meat, when we ate bread to the full, for you have brought us out into this desert to kill this whole assembly with hunger!”

16:4 Then the Lord said to Moses, “I am going to rain bread from heaven for you, and the people will go out and gather the amount for each day, so that I may test them. Will they will walk in my law or not? 16:5 On the sixth day they will prepare what they bring in, and it will be twice as much as they gather every other day.”

16:6 Moses and Aaron said to all the Israelites, “In the evening you will know that the Lord has brought you out of the land of Egypt, 16:7 and in the morning you will see the glory of the Lord, because he has heard your murmurings against the Lord. As for us, what are we, that you should murmur against us?”
