Couch

Hastings' Dictionary of the Bible

COUCH . See House, § 8 . The verb ‘to couch’ occurs in Deuteronomy 33:13 ‘the deep that coucheth beneath.’ The word means simply to lie down , but it is used almost exclusively of animals, as is the Heb. word also. The subterranean deep, says Driver, is perhaps pictured as a gigantic monster.
