Bloch made two major proposals for dealing with the series. First, she suggested a relative sequence for them based on a somewhat mechanical principle of “longer is later.” Although this may often be correct, it is just as likely that a given author may abbreviate as well as expand a source. Accordingly, her sequence may have to be held in some doubt pending further, more detailed analysis. Second, she noted that the basic story of Moses’ infancy in those rabbinic writings is known from Josephus and from pseudo-Philo (see next note), both of which can be dated with security to the end of the first century A.D. Thus, we must imagine a trajectory for the extra-biblical infancy story of Moses from at least the second half of the first century and on into those rabbinic texts still awaiting critical analysis for both manuscripts and contents.
