Acts 5:35-36

After the apostles had left the meeting room, Gamaliel addressed his colleagues with the traditional designation "Men of Israel" (cf. Acts 2:22). He warned his brethren to do nothing rash. He pointed to two similar movements that had failed when their leaders had died. Historians do not know anything about this Theudas, though he may have come to prominence shortly after Herod the Great’s death (ca. A.D. 4). [Note: See Longenecker, p. 228, or any of the conservative commentaries for discussion of the problem of this Theudas’ identification.] Josephus referred to a revolt led by one Theudas, but this occurred more than a decade after Gamaliel’s speech. [Note: Josephus, Antiquities of . . ., 20:5:1.]
