Joel 2:3

A fire, a most intense and parching heat, devoureth before them, in preparing for the desolation to follow, and behind them a flame burneth, the terrible, withering heat continuing even after the swarms of grasshoppers had passed. The land is as the Garden of Eden before them, like the beautiful park of paradise described in Genesis 2, and behind them a desolate wilderness; yea, and nothing shall escape them, the devastation would be so thorough.
