Psalm 78:17-25

Yet they sinned still more against him, rebelling against the Most High in the desert. They tested God in their heart by demanding the food they craved. They spoke against God, saying, “Can God spread a table in the wilderness? He struck the rock so that water gushed out and streams overflowed. Can he also give bread or provide meat for his people?” Therefore, when the LORD heard, he was full of wrath; a fire was kindled against Jacob; his anger rose against Israel, because they did not believe in God and did not trust his saving power. Yet he commanded the skies above and opened the doors of heaven, and he rained down on them manna to eat and gave them the grain of heaven. Man ate of the bread of the angels; he sent them food in abundance.
