The home of the fish

Enter, my beloved son! Enter, my fine son! Don't let the day go by, don't let the night come! The moonlight should not enter that house! But if the day has gone by and the night comes, enter and I will let you relax there; I have made the grounds suitable for you! Inside, I have fixed up a seat for you. My fish, no one who sleeps there will be disturbed; no one who sits there will get involved in a quarrel.
