'Load' in the Bible

A [mournful, inspired] oracle (a burden to be carried) concerning the beasts of the Negev (the South):Through a land of trouble and anguish,From where come lioness and lion, viper and [fiery] flying serpent,They carry their riches on the shoulders of young donkeysAnd their treasures on the humps of camels,To a people (Egyptians) who cannot benefit them.
