Exodus 16:18-20 International Children’s Bible (ICB)
18 Then they measured it. The person who gathered more did not have too much. The person who gathered less did not have too little. Each person gathered just as much as he needed.
19 Moses said to them, “Don’t keep any of it to eat the next day.” 20 But some of the people did not listen to Moses. They kept part of it to eat the next morning. But it became full of worms and began to stink. So Moses was angry with these people.
