do-min'-yun: In Eph 1:21; Col 1:16 the word so translated (kuriotes) appears to denote a rank or order of angels. The same word is probably to be so interpreted in Jude 1:8 (the King James Version and the Revised Version (British and American) "dominion"), and in 2Pe 2:10 (the King James Version "government," the Revised Version (British and American) "dominion"). See ANGEL.
