So spake the Seraph Abdiel faithful found, Among the faithless, faithful only he; Among innumerable false, unmov'd, Unshak'n, unseduc'd, unterrifi'd His Loyalty he kept, his Love, his Zeal; Nor number, nor example with him wrought To swerve from truth, or change his constant mind Though single.
― John Milton, Paradise Lost, 5:896-903
