ab’-gar, ab-ga’-rus, a-bag’-a-rus (Abgaros): Written also Agbarus and Augarus. A king of Edessa. A name common to several kings (toparchs) of Edessa, Mesopotamia. One of these, Abgar, a son of Uchomo, the seventeenth (14th?) of twenty kings, according to the legend (Historia Ecclesiastica, i.13) sent a letter to Jesus, professing belief in His Messiahship and asking Him to come and heal him from an incurable disease (leprosy?), inviting Him at the same time to take refuge from His enemies in his city, "which is enough for us both." Jesus answering the letter blessed him, because he had believed on Him without having seen Him, and promised to send one of His disciples after He had risen from the dead. The apostle Thomas sent Judas Thaddeus, one of the Seventy, who healed him (Cod. Apocrypha).
