Cloke
(HDB, under the word).
Figuratively: The word lent itself easily and naturally to figurative uses. We find Paul (1Th 2:5) disclaiming using "a cloak of covetousness" (compare 1Pe 2:16) and Jesus (Joh 15:22) saying, "Now they have no excuse ("cloak") for their sin." Some such usage seems common to all languages; compare English "palliate."
