'Speaker' in the Bible

The Speaker: Who is this coming up from the desert like a column of smoke, like a fragrant billow of myrrh and frankincense, every kind of fragrant powder of the traveling merchants?

The speaker went on to say, "This is a curse traveling across the whole earth. For example, according to the curse whoever steals will be removed from the community; or on the other hand (according to the curse) whoever swears falsely will suffer the same fate."
