“You will appoint a way for the sword to come to Rabbah of the children of Ammon, and to Judah, to Jerusalem the defenced.”
The watchers wait in suspense as they see what has been mapped out before them, and are aware of the decision that has to be made as to which rebel city will be advanced on first. What is the decision going to be? One way will take the sword to Rabbah in Ammon, the other will take it to Judah and Jerusalem waiting in fearful anticipation with its defences bristling. Both will of course eventually be involved (see Ezekiel 21:28).
