There were some Jews who believed in the prophecy of two Messiahs before, during, and after the time Christ. The cult at Qumran, and possibly the Essenes, along with some other sects, believed the Bible spoke of two messiahs because of the different qualities of them: one would suffer and be from the line of Joseph, while the other would be more of a warrior from the line of David. However, Jesus fulfilled both of these lineages, finished the work of the suffering messiah from the line of Joseph, and will return to fulfill his role as judge and warrior in the final days.
Paul clarifies the truth of the One Messiah beautifully here, in his epistle to the Ephesians:
“There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all.” ~Ephesians 4:4-6
~Song of Mary~
