4 Then said the Lord unto Moses, Behold, I will rain bread from heaven for you; and the people shall go out and gather a certain rate every day, that I may prove them, whether they will walk in my law, or no.

5 And it shall come to pass, that on the sixth day they shall prepare that which they bring in; and it shall be twice as much as they gather daily.

After Israel’s grumbling the Lord gave Moses His answer, and note how He returns faithfulness for faithlessness. The Israelites had suddenly abandoned their trust in God, certain that He had brought them to ruin. They had become utterly hopeless and despondent. But though they had abandoned their faith in Him, God was still faithful in helping and preserving them. By a miracle He would rain bread down, literally a blessing from heaven. A reward in place of punishment.

There was going to be a catch to all this, though. God said that with this blessing would also come a test, to “prove them, whether they will walk in my law, or no.” And so He listed out some requirements for how the Israelites were to respond to this manna from heaven. There would be a virtually unlimited source available to them, but they were only to gather the necessary portion day-by-day, except on the sixth day they could gather twice as much, so that they could eat on the sabbath. These instructions would later be reiterated in more explicit detail, so that there could be no misunderstanding among the Jews.

It seems to me that God was making a point with this test. Did the Israelites complain and lose faith simply because they didn’t feel provided for, or because of some pull towards infidelity that lived deep inside of them? Would they keep His commandments once He had provided for them, or would they still feel compelled to hold something back? Was their faithlessness really about a problem with God, or was it a problem in themselves? We will see for ourselves as we read on.
