122:0.1 It will hardly be possible fully to explain the many reasons which led to the selection of Palestine as the land for Michael's bestowal, and especially as to just why the family of Joseph and Mary should have been chosen as the immediate setting for the appearance of this Son of God on Urantia.
122:0.2 After a study of the special report on the status of segregated worlds prepared by the Melchizedeks, in counsel with Gabriel, Michael finally chose Urantia as the planet whereon to enact his final bestowal. Subsequent to this decision Gabriel made a personal visit to Urantia, and, as a result of his study of human groups and his survey of the spiritual, intellectual, racial, and geographic features of the world and its peoples, he decided that the Hebrews possessed those relative advantages which warranted their selection as the bestowal race. Upon Michael's approval of this decision, Gabriel appointed and dispatched to Urantia the Family Commission of Twelve—selected from among the higher orders of universe personalities—which was intrusted with the task of making an investigation of Jewish family life. When this commission ended its labors, Gabriel was present on Urantia and received the report nominating three prospective unions as being, in the opinion of the commission, equally favorable as bestowal families for Michael's projected incarnation.
122:0.3 From the three couples nominated, Gabriel made the personal choice of Joseph and Mary, subsequently making his personal appearance to Mary, at which time he imparted to her the glad tidings that she had been selected to become the earth mother of the bestowal child.
