Of whom the world was not worthy--So far from their being unworthy of living in the world, as their exile in deserts, &c., might seem to imply, "the world was not worthy of them." The world, in shutting them out, shut out from itself a source of blessing; such as Joseph proved to Potiphar (Gen 39:5), and Jacob to Laban (Gen 30:27). In condemning them, the world condemned itself. caves--literally, "chinks." Palestine, from its hilly character, abounds in fissures and caves, affording shelter to the persecuted, as the fifty hid by Obadiah (Kg1 18:4, Kg1 18:13) and Elijah (Kg1 19:8, Kg1 19:13); and Mattathias and his sons (1 Maccabees 2:28, 29); and Judas Maccabeus (2 Maccabees 5:27).
