1 Corinthians 10:1-4, 9

Brothers and sisters, I want you to know what happened to our ancestors who followed Moses. They were all under the cloud and all went through the sea. They were all baptized as followers of Moses in the cloud and in the sea. They all ate the same spiritual food, and all drank the same spiritual drink. They drank from that spiritual rock that followed them, and that rock was Christ.

We must not test Christ as some of them did; they were killed by snakes.
