1 Corinthians 10:1, 2, 3, 4

For I do not want you to be ignorant of the fact, brothers and sisters, that our ancestors were all under the cloud and that they all passed through the sea.

They were all baptized into Moses in the cloud and in the sea.

They all ate the same spiritual food

and drank the same spiritual drink; for they drank from the spiritual rock that accompanied them, and that rock was Christ.
