Moreover, brethren, I want not that you should be ignorant, how that all our fathers were under the cloud, and all passed through the sea;

Cyprian of Carthage
AD 258
And that that sea was a sacrament of baptism, the blessed Apostle Paul declares, saying, "Brethren, I would not have you ignorant how that all our fathers were under the cloud, and all passed through the sea, and were all baptized unto Moses in the cloud and in the sea; "and he added, saying, "Now all these things were our examples.".
Likewise in the first Epistle of Paul to the Corinthians: "Brethren, I would not that ye should be ignorant, that all our fathers were under the cloud."
