The noun hyetos denotes rain, particularly a heavy downpour as distinguished in classical Greek from continuous drizzle (psekados) or steady rain (ombros). In the New Testament every occurrence carries theological freight: God gives rain from heaven as testimony to his goodness (Acts 14:17), rain falls on the earth and brings blessing to the faithful (Heb 6:7), Elijah's prayer both shuts the sky and opens it again to rain (Jas 5:18), and the two witnesses possess power to shut heaven so that no rain falls (Rev 11:6). Spanish lluvia, French pluie, and German Regen all converge on the single concept of rainfall, with no polysemy.
