כֹּֽה־אָמַ֞ר יְהוָ֣ה צְבָא֗וֹת צ֣וֹם הָרְבִיעִ֡י וְצ֣וֹם הַחֲמִישִׁי֩ וְצ֨וֹם הַשְּׁבִיעִ֜י וְצ֣וֹם הָעֲשִׂירִ֗י יִהְיֶ֤ה לְבֵית־יְהוּדָה֙ לְשָׂשׂ֣וֹן וּלְשִׂמְחָ֔ה וּֽלְמֹעֲדִ֖ים טוֹבִ֑ים וְהָאֱמֶ֥ת וְהַשָּׁל֖וֹם אֱהָֽבוּ׃ (פ)
’Thus saith the LORD of hosts: The fast of the fourth month, and the fast of the fifth, and the fast of the seventh, and the fast of the tenth, shall be to the house of Judah joy and gladness, and cheerful seasons; therefore love ye truth and peace.
Zohar
It is written "Dominion and dread are His; He makes peace in His heights" (Job 25:2) - this verse was raised by the group of friends. But "dominion" is Avraham, as it is written about him "you are the elect of E-lohim among us" (Genesis 23:6) and also "I will bless you and I will make your name great" (Genesis 12:2). "Dread" is Itzchak, as it is written "the dread of Itzchak was with me" (Genesis 31:42). "Makes peace in His heights" - this is Yaakov, as it is written "You gave truth to Yaakov" (Micah 7:20) and also "love truth and peace" (Zecharia 8:19) - truth and peace are tied to one another. And so he is the most complete of all.
