What are "Charavos"?
Malbim: They are Chorev (dry) places.
It seems that the verse discusses returning from Bavel. Why does Sefer Ezra not mention these miracles?
Mahari Kara: This discusses miracles that Hashem did for Yisrael when they left Egypt 1 . He will later redeem you from Bavel.
Mahari: This is a metaphor. Even though Olei Bavel were poor, Hashem supplied their needs as if water flowed from a rock...
Kli Paz: From the creation of the world, Hashem knew the path on which Yisrael will return from Bavel, therefore he arranged that there will be water there for them.
Malbim: Amidst telling of the return from Bavel, the Navi mentions splitting the sea and Yarden for Yisrael when they left Egypt.
Perhaps a support is that the previous verses are in the future or commands, and this verse is in the past. (PF) Radak left this question difficult.
