Jews like to take the Jewish year and assign to it a titular prediction.
This year, 5786, has been given an acronym (by Rabbi Y. Ginsburg) to suggest:
"It will be a year of 'Be fruitful and multiply'"
תהי׳ה שנת פרו ורבו
And what would the Gematria of that phrase predict, assuming its numerical find is significant?
The gematria of 1670 in Torah is found in only two verses:
Below are those verses and their translations:
1) Devarim (2:15)
וגם יד יהוה היתה בם להמם מקרב המחנה עד תמם
2) Parsha Shoftim (20:4)
כי יהוה אלהיכם ההלך עמכם להלחם לכם עם איביכם להושיע אתכם
1) Also the hand of the Lord was upon them, to destroy them from the midst of the camp, until they were consumed.
2) For the Lord, your God, is the One Who goes with you, to fight for you against your enemies, to save you.
So while the Jews will continue to be productive and multiply, these verses predict the end of terror - the end of Hamas and the end of hate of the Jewish People, may it all come true this year.
