The third of the Sheva d’Nechemta, the Haftarot of Consolation, from Yeshayahu describes a time without war or terror, when the leadership of the Jewish People will reach the level of King David.
Linear annotated translation of the Haftarah of Re’eh
Here is what we learn from Parshat Re’eh regarding the standard for leaders of the Jewish People.
and after you’ve read that, you can consider how a this Midrash fits in with the ideas presented there:
אמר רבי אלעזר אמר רבי חנינא: תלמידי חכמים מרבים שלום בעולם שנאמר +ישעיהו נ”ד+ וכל בניך למודי ה’ ורב שלום בניך אל תקרי בניך אלא בוניך
R’ Eliezer said in the name of R’ Hanina: Torah scholars increase peace in the world, as it says, “All your children will be taught by Hashem; great will be the peace of your children”. Do not read “your children”, read it as “your builders”. (Talmud Bavli Brachot 64a)
