Deuteronomy 8:3 says man does not live on bread alone but on what?

Answer: Every word of the LORD

God humbled Israel and fed them manna so they would understand that man lives on every word that comes from the mouth of the LORD.

“He humbled you, and in your hunger He gave you manna to eat, which neither you nor your fathers had known, so that you might understand that man does not live on bread alone, but on every word that comes from the mouth of the LORD.”— Deuteronomy 8:3 (BSB)
