D'var Torah: "It is a night in which HaShem guarded them to take them out from the land of Egypt; this night HaShem guards the Children of Israel throughout their generations" (Shemos 12:42). The Torah mentions HaShem's guarding the Children of Israel twice in this verse. The first guarding refers to HaShem's protection of the Children of Israel when the deadly plague struck every firstborn Egyptian at midnight. The second guarding of the Children of Israel refers to the future redemption. The Torah prophetically tells us that HaShem will protect the Children of Israel during the turbulent events prior to the Messianic era.
Moral: The uncertainty of what will take place in "the end of days" is unsettling. Thankfully, the Torah comforts us with HaShem's guarantee to protect the Children of Israel in the end of days. Just as He protected us in the time of mortal danger in Egypt, so too, HaShem will protect and shield the People of Israel at the time of the future redemption.
Application: Sense the joy the Children of Israel experienced in Egypt at midnight when HaShem spread His wings of protection over them, saving them from death. Be comforted in knowing that HaShem will again spread His wings of protection over us at the time of our final redemption, just as miraculously as He did in Egypt. HaShem will reveal His love to Klal Yisrael, and He will protect, save, and redeem His beloved Children of Israel.
