21 Heb “a shelter it will be for shade by day from heat, and for a place of refuge and for a hiding place from cloudburst and rain.” Since both of the last nouns of this verse can mean rain, they can either refer to the rain storm and the rain as distinct items or together refer to a heavy downpour. Regardless, they do not represent unrelated phenomena.
