Exodus 16 - 18

God gives the people manna from heaven that would continue for 40 years.

In John 6:41 Jesus said that He was that bread that came down from heaven, and in Matthew 6:11 Jesus tells us to pray each day for the bread that God will give us that day, which is both physical and spiritual.

God also brings forth water from the Rock at Horeb (Sinai), which would run like a river for 40 years in the desert, providing water for 1-2 million Israelites.

Jesus was that Rock (1 Corinthians 10:4), and He is the source of eternal water, so that everyone who drinks of Him will never thirst again (John 4:14).
