The threatenings of God's word press heavily upon the wicked, and are a sore burden, too heavy for them to bear. The persons brought together to lay Babylon waste, are called God's sanctified or appointed ones; designed for this service, and made able to do it.
They are called God's mighty ones, because they had their might from God, and were now to use it for him. They come from afar. God can make those a scourge and ruin to his enemies, who are farthest off, and therefore least dreaded.
