Rabbi Yehoshua of Sikhnin said in the name of Rabbi Levi: Great is peace for all blessings are sealed with peace: The reading of the Shema — "spreads the shelter of peace." The [standing] prayer — "He who makes peace." The Priestly Blessing — "and grant you peace" (Numbers 6:26). But I only know this regarding blessings; so where do we derive this for sacrifices? We learn to say, "This is the Torah of the burnt-offering, of the grain-offering, etc. and the sacrifice of the peace-offering" (Leviticus 7:37). But I only know this in general; so where do we derive this in detail? We learn to say, "This is the law of the burnt-offering" (Leviticus 6:2), "This is the law of the grain-offering" (Leviticus 6:7), "This is the law of the sin-offering" (Leviticus 6:18), "This is the law of the guilt-offering" (Leviticus 7:1), "This is the law of the peace-offering" (Leviticus 7:11). But I only know this for individual sacrifices; so where do we derive this for communal sacrifices? We learn to say "Do these for the Lord on your set times, etc.," [yet it finishes with "peace-offerings" (Numbers 29:39). I only know this in this world; so from where do we derive this in the next world? We learn to say, "I will extend to her peace like a river" (Isaiah 66:12). The Rabbis said: Great is peace, for when the messianic king will come, he will only open with peace, as it is written, "How pleasant on the mountains are the feet of the messenger proclaiming peace" (Isaiah 52:7). And why did they see fit to say the Priestly Blessing after the blessing of thanksgiving (in the silent prayer)? As it is written, "And Aharon lifted up his hand toward the people and blessed them, and he came down from sacrificing the sin-offering" (Leviticus 9:22). And why did they see fit to says the blessing of "Grant peace," after the Priestly Blessing ? As it is stated, "And they shall put My name upon the children of Israel, and I will bless them" (Numbers 6:27). The blessing of the Holy One, Blessed be He, is peace, as it is stated, "The Lord blesses His people with peace" (Psalms 29:11). Rabbi Yehoshua ben Levi says: From where is it derived that the Holy One, Blessed be He, desires the Priestly Blessing? As it is stated, "So shall they put My name upon the Children of Israel, and I will bless them" (Numbers 6:27).
