Second reading
I do not want you to be unaware, brothers and sisters, that our ancestors were all under the cloud; all passed through the sea; all were baptized into Moses in the cloud and in the sea; all ate the same spiritual food, and all drank the same spiritual drink. For they drank from the spiritual rock that followed them, and the rock was Christ.
Nevertheless, God was not pleased with most of them, and they were struck down in the wilderness.
Now these things occurred as examples for us, so that we might not desire evil as they did. And do not complain as some of them did, and were destroyed by the destroyer.
These things happened to them to serve as an example, and they were written down to instruct us, on whom the ends of the ages have come. So if you think you are standing, watch out that you do not fall.
