In Torah portion KiTavo, Hashem lists many curses that will betake Jewish people should they stray from Torah's ways. After mentioning several such horrible circumstances, there's an interruption, a break in the string of horror events. There is this one verse that's interjected as a promise of Hashem. Then Hashem continues with a much longer list of horrible events the Jews might suffer.
This one interjected verse is Hashem's promise to exact these miseries upon the Jewish people should they not follow Torah's precepts, saying that it will be a forever promise.
The implication of this verse is to remind Jews that they have a choice in the matter, for all generations to come.
This single verse in the midst of many frightful verses, says, as I understand the words to mean, “It can be good or bad, and you and generations after will always have this switch you can turn off or on, to control your destiny. It could be horrible at one point, but suddenly, as easily as a flip of the switch, Jews can immediately reverse the tide to flow in the opposite direction, to make it all good. Literally the possuk (KiTavo 28:46) says, “And they will be as a sign and a wonder, upon you and your offspring, forever.” "They" refers to the curses, "sign" refers to the actual tragedies, and "wonder" I figure could mean when it's all good, and this promise will stand "for all generations", today's included.
It's as if Hashem is telling us, after having begun His long list of tragedies that can happen, a by-the-way sentence in midstream, that we should know that all this bad stuff here to be recounted need not befall the Jews if only they choose to go in Torah's ways.
The gematria of this one verse, might give us a hint that points to the same thesis. The gematria of KiTavo 28:46, 1573, we find that it is equal to the value of 7 words inside a verse found in Esther 9:1, namely, the phrase:
"ונהפוך הוא אשר ישלטו היהודים המה בשנאיהם"
This phrase from the Purim story is exactly appropriate because it alludes to the miraculous turnaround we experienced in Persia under Queen Esther and King Achashverosh, and that which we see happening in Judaism today.
Today too Hashem is remodeling the lives of Jews everywhere. Until only a century ago, Jews were hounded whereever they lived, usually oppressively, yet today there's hardly a Jew anywhere on the globe that cannot be free and do as he wishes, without any oppression at all.
And the most recent events, as Israel has triumphed miraculously against so many of its enemies in a matter of weeks and months, while destroying Iran's (x-Persia) nuclear might and threat from all its proxies in the North, South and West of Israel - we are are the good path - on a great path towards final redemption, it seems quite clear.
Open your eyes folks, we're into the new Era of Final Redemption and soon will greet our King Moshiach.
