Bart, two points for you attention. First, the title "anointed one," is translated Messiah in Hebrew and Christ in Greek. In Israel the prospective king was anointed with oil. So anointing in Israel was closely associated with kingship not priesthood (see Saul, David, Solomon, etc.). Second point, notice the context, i.e., the rest of Daniel. In Dan. 2:44 , 45 God’s Kingdom is mentioned. For this kingdom a king needs to be appointed. In Dan. 4:24 , 25 mentions that in time God will appoint a king of his choosing. This king is identified in Dan. 7:13 , 14 as “someone like a son of man.” Jesus often referred to himself as “the son of man.” The time for his appearance as designated king is predicted at Dan. 9:24-27 . Afterwards the city and the temple were to be destroyed.
Phizzy, the earliest Christian mention of the Seventy Weeks prophecy is in the Epistle of Barnabas (ca. A.D. 100). Otherwise no extended discussion of this prophecy has been found in Christian literature before the late second century A.D. Prior to this, however, several Jewish writings include chronological schemes, some of which are based on the passage (e.g. that of the Essenes). The writers of the DSS, like Leolaia, believed in two messiahs, one a king and one a priest. The earliest clear Christian reference to Daniel 9:24-27 is by Irenaeus in his Against Heresies (ca. A.D. 180). In Book 5.25.3 he clearly linked the prophecy of the little horn in Daniel 7 to 2 Thessalonians 2 , and he indicated that the Antichrist will be in power three and a half years, etc.
