Where the nations stand is not a New Testament invention. It runs from the first promise made to Abram, through a mixed multitude walking out of Egypt, through a Moabitess who would not go home, through Isaiah telling the stranger he is not separated, and only then into Acts and the letters. Ten days, read in that order, so the argument the apostles had lands the way it landed on them: not as a new idea, but as something the prophets had already said.
