Israel, The Most High God's chosen people, had just been freed from oppression and bondage in the mighty land of Egypt, and in Deuteronomy 28:68, Egypt is mentioned again, to warn Israel that they would return there if they disobeyed the commandments of their Elohim. Only this time however, Moses makes an interesting distinction, and tells them that when they return to Egypt, that they will be taken there by ships! Now, Israel did not go in to Egypt on ships the first time, why? Mainly because in the region of the Land of Canaan,

The Promised Land, and 

where they were in the time Joseph ruled as

governor in Egypt, a ship was not needed to get 

there! Even after the Exodus, and the establishing

 of Israel, travel to Egypt was mostly done

by land. So why did

The Most High say that they would return there

by ships? I'll tell you, in this verse Egypt is used metaphorically to represent slavery. TMH refers to Egypt as the land of slavery or The House of Bondage in Exodus 20:2 and its repeated in Deuteronomy 5:6, Joshua 24:17 and Micah 6:4..I am the LORD thy God, which brought thee out of the land of Egypt, from the house of bondage.  So what Moses was prophesying here was that a time would come when they would fall away from their Elohim and obeying His Commandments, and that in that day, it will come to pass that they would return to Egypt or bondage (slavery), but that this time, they would be taken captive by ships.
