(Heb., Servant of God.) The name of an angel mentioned by the Jewish Kabbalists. He is represented in Milton's *Paradise Lost*, Book V, as one of the seraphim, who, when Satan tried to stir up a revolt among the angels subordinate to his authority, alone and boldly withstood his traitorous designs:
Among the faithless, faithful only he;
Among innumerable false, unmoved,
Unshaken, unreduced, unterrified,
His loyalty he kept, his love, his zeal.
The name Abdiel became the synonym of honor and faithfulness.
