Deuteronomy 28:68

68.And the Lord shall bring thee into Egypt again with ships. We know that the people were so driven about in the desert amidst divers perils, that they only escaped from it in safety by extraordinary miracles. It was therefore a thing most highly to be desired by their posterity, that they should never be carried back into those mighty depths. He who had once rescued them from those deaths might indeed often be their deliverer; but in order to make His blessing at that time more memorable, He had provided that they should never return into that wilderness. To bring them back into it again, was, then, in a manner to blot out the grace of redemption. If any object that it was impossible that the people should be conveyed in ships through dry places, the reply is easy, that since mention is made of the captivity, there is no absurdity in their being carried in ships and landed on the shore which (256) belongs to the plain of Moab, so as to finish their journey by wandering through the desert on foot.

Finally, he shews how melancholy their condition would be, since they would desire to sell themselves to their enemies, and would find none to buy them on account of their vileness.
