Exo 16:4  Then the LORD said to Moses, “Behold, I am about to rain bread from heaven for you, and the people shall go out and gather a day’s portion every day, that I may test them, whether they will walk in my law or not. 

In Exodus 16:4 God sets out a test for Israel. He commands them to gather only one day’s worth of rations at a time. The purpose is for God to learn if Israel trusts God or not. God is testing the people to learn something about them.
