"After listening to the king, they [the wise men] went on their way. And behold, the star that they had seen when it rose went before them until it came to rest over the place where the child was. When they saw the star, they rejoiced exceedingly with great joy. And going into the house they saw the child with Mary his mother, and they fell down and worshipped him.
