1 Corinthians 10:1-4

I don’t want you to forget, dear brothers and sisters, about our ancestors in the wilderness long ago. All of them were guided by a cloud that moved ahead of them, and all of them walked through the sea on dry ground. In the cloud and in the sea, all of them were baptized as followers of Moses. All of them ate the same spiritual food, and all of them drank the same spiritual water. For they drank from the spiritual rock that traveled with them, and that rock was Christ.
