The idea of baptism as a process
of submersion in water is achieved by Paul in the case of the crossing of the
Red Sea by the simultaneous reference to the cloud and the sea. The cloud is of
watery substance and so Israel is veritably surrounded by water. (Ulrich W.
Mauser, Christ in the Wilderness [Studies in biblical Theology First
Series No. 39; London: SCM Press, 1963; repr., Eugene, Oreg.: Wipf and Stock,
2009], 64 n. 4)
