Psalm 105:40b He gave them food from heaven in abundance.
Exodus 16:14-15, 31-33 When the layer of dew lifted, there on the surface of the wilderness was a fine flaky substance, as fine as frost on the ground. When the Israelites saw it, they said to one another, ‘What is it?’ For they did not know what it was. Moses said to them, ‘It is the bread that the Lord has given you to eat. The house of Israel called it manna; it was like coriander seed, white, and the taste of it was like wafers made with honey. Moses said, ‘This is what the Lord has commanded: “Let an omer of it be kept throughout your generations, in order that they may see the food with which I fed you in the wilderness, when I brought you out of the land of Egypt.”’ And Moses said to Aaron, ‘Take a jar, and put an omer of manna in it, and place it before the Lord, to be kept throughout your generations.’
1 Corinthians 10:1-3 I do not want you to be unaware, brothers and sisters, that our ancestors were all under the cloud, and all passed through the sea, and all were baptized into Moses in the cloud and in the sea, 3 and all ate the same spiritual food.
