“The Jews' enemies [were] made their friends. When they received this order from the king they came with as much haste to encourage and assist the work as their predecessors had done to put a stop to it (Ezra 4:23). What the king ordered they did, and, because they would not be thought to do it with reluctance, they did it speedily. The king's [support] made them, contrary to their own inclination, [supportive] too.” -Matthew Henry
