Deuteronomy 8:2-4

2Remember how the Lord your God led you all the way across the desert. He took care of you for 40 years. He caused many troubles to come and to test you. He did that to see if you would trust him. He wanted to know whether you would continue to obey his commands.

3He caused you to become hungry and then he fed you with manna. Neither you nor your ancestors had ever seen this food before. In this way, he taught you that food alone cannot cause people to live. They need to hear every word that the Lord speaks. That is what gives them true life.

4During those 40 years in the desert, your clothes did not spoil. Your feet did not become big with pain.
