Yes, he humbled you by letting you go hungry and then feeding you with manna, a food previously unknown to you and your ancestors. He did it to teach you that people do not live by bread alone; rather, we live by every word that comes from the mouth of the Lord.
It is the same with my word. I send it out, and it always produces fruit. It will accomplish all I want it to, and it will prosper everywhere I send it.
A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart. What you say flows from what is in your heart.
