Exodus 16:4

Then he cried out to Yahweh, and Yahweh showed him a tree; and he threw it into the waters, and the waters became sweet. There He set for them a statute and a judgment, and there He tested them.

And the sons of Israel saw it and said to one another, “What is it?” For they did not know what it was. And Moses said to them, “It is the bread which Yahweh has given you to eat.

“You gave bread from heaven for them for their hunger, You brought forth water from a rock for them for their thirst, And You said to them to enter in order to possess The land which You swore to give them.

He rained down manna upon them to eat And gave them grain from heaven.

“Our fathers ate the manna in the wilderness; as it is written, ‘He gave them bread from heaven to eat.’”
