Isaiah 30:6

The burden of the beasts of the South, of the hippopotamus, as the emblem of Egypt. Into the land of trouble and anguish, through the desert between Palestine and Egypt, with its many disagreeable and dangerous features, from whence come the young and old lion, the viper and fiery flying serpent, these animals representing some of the great dangers of the wilderness, they, the ambassadors of Judah, will carry their riches, the treasures with which they intend to buy Egypt's help, upon the shoulders of young asses and their treasures upon the bunches of camels, upon their humps, their strongest pack-animals being pressed into service for this purpose, to a people that shall not profit them, who would leave them in the lurch at the very time when they would need assistance most.
