Psalms 78:22

²⁰ Behold, he smote the rock, that the waters gushed out, and the streams overflowed; can he give bread also? can he provide flesh for his people?

²¹ Therefore the LORD heard this, and was wroth: so a fire was kindled against Jacob, and anger also came up against Israel;

Because they believed not in God, and trusted not in his salvation:

²³ Though he had commanded the clouds from above, and opened the doors of heaven,

²⁴ And had rained down manna upon them to eat, and had given them of the corn of heaven.
