Behold, I have made thee small. Here is the effect of the summons. So in Jeremiah 49:15, "For, lo, I will make thee small." Jehovah is the Speaker, and he regards the future as past. What he determines is as good as accomplished. At this time the Edomites were a powerful nation, and possessed an almost impregnable seat at Petra. Small; in numbers, territory, honour.
Edom had prided herself in the strength of her position; but this shall not secure her from destruction when the Lord wars against her.
