On the words, vayehi beshalach, “And it was that when Pharaoh sent out the nation” (13:17), the Midrash states that vayehi alludes to a cry of woe (vayi), for Moshe was grieved when saw that the redemption was incomplete and the Jews would have to suffer further exile in a long and difficult road to the final redemption. This is associated with the previous verses (that conclude last week’s parshah) that contain the command to place tefillin on the head, and on the arm opposite the heart. The need for tefillin is a reflection of the incompleteness of the Exodus. Had the Exodus been complete, G-d would have installed the Torah within our hearts and minds and the external sign of tefillin would not have been necessary. Indeed, in the final and complete redemption, this will be granted to us, as stated in the verse, “I will set My law within them and I will inscribe it upon their hearts, and I will be their G-d and they will be My people. No longer will one teach his neighbor or one his brother, saying, ‘Know G-d,’ for they will all know Me from their smallest to their greatest” (Yirmiyah 31:32-33).
