Ecclesiastes 4:11

11. How can one be warm The ordinary people of Palestine to this time, as did all the ancients, lie down at night in the usual clothing of the day. The country has hot days and cold nights, and a traveller is annoyed at the complaints of his men arising from insufficient protection. The frost consumes them by night, and they crowd together for warmth. The houses formerly had open lattice instead of glass windows, so that the cold night air was felt within, and the sleepers on mats and carpets suffered from the chill. There is no allusion here to husband and wife. Night-dresses, distinct from the clothing worn by day, were first introduced by the French, and in quite modern times.
