RABBI WEIN ON YITRO

It is well known that there is a difference of opinion as to whether Yitro’s arrival in the camp of Israel in the desert occurred before or after the revelation and granting of the Torah at Mount Sinai. Even if we say that Yitro arrived before the momentous event of Mount Sinai and that the Torah is recording events in a chronological manner, it still is difficult for us to understand. Why is this most important event in Jewish history as outlined for us in the Torah, be preceded by a rather mundane description of Yitro’s arrival and reception in the camp of Israel? Would it not be more effective to highlight the revelation at Sinai immediately at the beginning of the parsha? And this appears to be especially true since the parsha goes into great detail and some length in describing the circumstances and experience of the revelation at Sinai. Why is there such an apparent emphasis on Yitro and his arrival?
