וְאֶתְכֶם לָקַח יְהֹוָה וַיּוֹצִא אֶתְכֶם מִכּוּר
“You hath H’Shem taken and brought forth out of the iron furnace.”
– Deuteronomy 4:20, JPS 1917 Tanach
Rashi explains, “a כור is a vessel in which one refines gold” (sefaria.org). Moshe’s choice of words, attempts to impress upon the new generation, that the nisyanos (challenges) in Egypt, were meant to serve as a means to refine the people. Consider that when gold is placed in “a refiner’s fire,” the impurities are drawn out; what remains is pure. The soul is also refined, through the challenges of life, in order to be free from taint.
Joseph, serves as an example, who went ahead of the children of Israel into Egypt, endured many challenges, “until the time that His word came to pass; the word of the L-rd had tested him” (Psalms 105:19). His character was refined in the refiner’s fire, in preparation for his role as a leader in Egypt, only second to Pharoah. In this manner, he was tested, until his prophetic dreams were fulfilled by H’Shem, through the circumstances of his life.
Moshe continues, “H’Shem shall scatter you among the peoples, and ye shall be left few in number among the nations, whither H’Shem shall lead you away” (Deuteronomy 4:27). “From thence ye will seek the L-RD thy G-d; and thou shalt find Him, if thou search after Him with all thy heart and with all thy soul” (Deuteronomy 4:29).
בַּצַּר לְךָ וּמְצָאוּךָ כֹּל הַדְּבָרִים הָאֵלֶּה בְּאַֽחֲרִית הַיָּמִים וְשַׁבְתָּ עַד־יְהֹוָה אֱלֹהֶיךָ וְשָֽׁמַעְתָּ בְּקֹלֽוֹ׃
In thy distress, when all these things are come upon thee in the end of days, thou wilt return to H’Shem thy G-d, and hearken unto His voice; for the L-RD thy G-d is a merciful G-d; He will not fail thee.”
– Deuteronomy 4:30-31
“G-d ventured to go and take Him a nation from the midst of another nation, by trials, by signs, and by wonders” (Deuteronomy 4:34). So too, will he lead us out of exile. As the sages note, the time that will precede the Final Redemption, will mirror the plagues that preceded the first redemption, when B’nei Yisrael was led out of Egypt. As we approach the building of the third temple, during a time of great nisyanos (challenges) for all the world (Daniel 12:2), we shall endure.
