Matthew's Messianic Shepherd-King

In two places in the First Gospel (Matt 10:5b-6; 15:24) the Messianic mission of Jesus and his disciples is limited to a group called 'the lost sheep of the house of Israel'. In light of Matthew's intense interest in Jesus' Davidic Messiahship and the Jewish Shepard-King traditions surrounding King David it is argued that the 'lost sheep of the house of Israel'refers to remnants of the former northern kingdom of Israel who continued to reside in the northern region of the ideal Land of Israel.
