As Moses leads the children of Israel toward the promised land, he must deal with their constant grumbling. Even after God provides food and water, they continue to complain. Moses encourages the people to trust God, but their lack of faith results in their wandering for many years.

But part way though the project, Antoni is called away, so Megan tries to finish the job herself, with disastrous results. “What’s a Manna with You?” teaches the lesson of being content with what we have.
