Exodus 16:2-4

16:2 The entire company of Israelites murmured against Moses and Aaron in the desert. 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?
