1 ROM 11:33 It is possible that ἀνεξεραύνητος and ἀνεξιχνίαστος are somewhat different in meaning, but they appear to be used in ROM 11:33 as very close synonyms. From a semotactic standpoint, however, it is easy to see why ἀνεξεραύνητα would be combined with κρίματα and ἀνεξιχνίαστοι would be combined with ὁδοί.
