The word manna comes from the Hebrew words man hu, which mean "What is it?" God provided this food in a miraculous way to teach his people to depend fully on him (Exodus 16:1–30; Numbers 11:4–9).
Manna represented the word of God. God’s word is even more important for life and well-being than food.
man does not live on bread alone: Jesus quoted these words when Satan tempted him (Matthew 4:4; Luke 4:4). Jesus used this Scripture to answer Satan and show that people need God’s word more than physical food.
