Heres something interesting....
did the rock that the Israelites got water from while travelling in the desert travel with them?
Jewish tradition says yes, and this verse might suggest it did as well.....

1 Cor 10: 1 For I do not want you to be ignorant of the fact, brothers, that our forefathers were all under the cloud and that they all passed through the sea. 2They were all baptized into Moses in the cloud and in the sea. 3They all ate the same spiritual food 4and drank the same spiritual drink; for they drank from the spiritual rock that accompanied them, and that rock was Christ. 5Nevertheless, God was not pleased with most of them; their bodies were scattered over the desert.
