To the Corinthians, Paul recalled that just as all the Jews
of the Exodus (including children) were baptized into Moses
by passing through the Red Sea, they were actually being
blessed by Christ.
1 Corinthians 10:1-4
I do not want you to be unaware, brothers, that our
ancestors were all under the cloud and all passed
through the sea, and
all of them 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 a spiritual rock that followed them,
and the rock was the Christ.
