637. And they shall have no rest day and night, who adore the beast and his image, and if anyone shall have received the mark of his name, signifies a perpetual state of things undelightful with those who acknowledge that faith and receive its doctrine, confirm it and live according to it. By "having no rest day and night," is signified their perpetual state in things undelightful after death, because just before it speaks of their torment. By "day and night" is signified all time; and, in the spiritual sense, in every state, thus perpetually, for "day and night" in that sense signify states of life (n. 101, 476). That by "adoring the beast and his image, and receiving the mark of his name," is signified to acknowledge that faith, receive its doctrine, confirm it in oneself, and live according to it, may be seen above (n. 634), where similar things are said.
