אבות א, יח - סולם של ערכים

(18) Rabban Shimon ben Gamaliel used to say: on three things does the world stand: On justice, on truth and on peace, as it is said: “execute the judgment of truth and peace in your gates” (Zechariah 8:16).

(9) Said Rabbi Shimon ben Yoḥai: Great is peace, for all blessings are included with it, "Adonai grants strength to His people, Adonai blesses his people with peace" (Psalm 29:11). Ḥizkiyah said two things. Ḥizkiyah said: Great is peace, for all the commandments are written this way: "When you see" (Exodus 23:5), "when you encounter" (Exodus 23:4), "when you come across" (Deuteronomy 22:6). If a commandment comes to you you are bound to do it, but if not you are not bound to do it. But here it says "Seek peace and pursue it" (Psalm 34:15) – seek it for your place, and pursue it for other places. Ḥizkiyah said also: Great is peace, for of all the encampments it is written thus (Numbers 33) "And they set out... and they encamped" – they would set out divided and would encamp divided. When they all came before Mt. Sinai it was done as one encampment, as it is written (Exodus 19:2) "And Israel encamped there"—it isn't written "And the Israelites encamped there" in the plural, but "and Israel encamped there" in the singular!—Because of this the Holy Blessed One said, "Here is the gate where I will give the Torah to My children."...Bar Kappara said: Great is peace, for the scriptures use words of fiction in the Torah so as to impose peace between Abraham and Sarah, as it is written "After I am withered shall I have pleasure? And my husband is so old!" (Genesis 18:12) But to Abraham He didn't say that but rather "And I am so old!" (Genesis 18:13)...Said Rabbi Shimon ben Gamliel: Great is peace, because the writings spoke works of fiction in the Torah to impose peace between Joseph and his brothers, as it is written (Genesis 50:17) “Thus say to Yosef, please forgive” - but we do not find Jacob commanding any such thing! Said Rabbi Yosei the Galilean: Great is pace, for even in a time of war we only open with peace, as it is written (Deuteronomy 20:10) "When you approach a city to make war on it, call out to it for peace." Said Rabbi Yudan son of Rabbi Yosei: Great is peace, for the name of the Holy Blessed One is called peace, as it is written "And he called it "Adonai is peace" (Judges 6:24). Said Rabbi Tanḥum son of Yudan, from here we derive that it is forbidden for one to call out "Peace" to a companion in a filthy place. Taught Rabbi Yishmael: Great is peace, for even the Great Name written in holiness, the Holy Blessed One said to blot out in water so as to impose peace between husband and wife. (See Numbers 5:19-23). Rabbi Meir was sitting and discoursing on Shabbat evening. There was this one woman who would sit and listen to him give his lecture. Once she waited until the lecture ended, went home, and found the light had gone out. Her husband said to her, "Where have you been?" She said to him, "I was sitting and listening to the voice of the lecturer." He said to her, "Thus and more I vow: I will not let you enter here until you go and spit in the lecturer's face!" She stayed away one Shabbat, another, a third. Her neighbors said to her, "Are you still angry at each other? Let's come with you to the lecture." When Rabbi Meir saw them, he figured it out through the holy spirit. He said to them, "Is there here a woman knowledgeable in treating eyes?" Her neighbors said to her, "If you go spit in his eye you will unbind your husband." When she sat down in front of him she became afraid of him, and said to him, "Rabbi, I am not knowledgeable in treating eyes." He said to her, "Even so, spit in my eye seven times, and I will be cured." She did so. He said to her, "Go tell your husband you told me to do it once and I spat seven times. His disciples said to him, "Rabbi, should people thus abuse the Torah? Couldn't one of us offered a treatment for you?" He said to them, "Is it not enough for Meir to be like his Maker?" For it had been taught: Great is peace, for even the Great Name written in holiness, the Holy Blessed One said to blot out in water so as to impose peace between husband and wife." Said Rabbi Shimon ben Ḥalafta: Great is peace, for when the Holy Blessed One created His universe He made pace between the upper and lower parts. On the first day He created some of the upper and lower parts, as it is written "In the beginning God created the heavens and the earth" (Genesis 1:1). On the second He created some of the upper parts, as it is written "And God said, 'let there be a firmament'" (Genesis 1:6). On the third He created some of the lower parts, as it is written, "And God said, 'gather the waters'" (Genesis 1:9). On the fourth some of the upper parts — "Let there be lights in the heavenly firmament" (Genesis 1:14). On the fifth He created some of the lower parts — "And God said, 'Let the waters swarm'" (Genesis 1:20). On the sixth He came to create humanity. He said, "If I create him from more upper parts, then the upper parts will outnumber the lower by one creation. If I create him from more lower parts, then the lower parts will outnumber the upper by one creation." What did He do? He made him from upper parts and from lower parts, as it is written "And Adonai God created humanity from the dust of the earth" (Genesis 2:7) — lower parts, "and blew into his nostrils the breath of life (Genesis 2:7) — upper parts. Rabbi Manei of Sh'av and Rabbi Yehoshua of Sikhnin said in the name of Rabbi Levi: Great is peace for all blessings and goodnesses and mercies that the Holy Blessed One gives to Israel 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). And I only know this regarding blessings, so where do we derive this for sacrifices? "This is the Torah of the burnt-offering, of the grain-offering, and of the sin-offering, and of the guilt-offering, and of the fulfillment-offerings, and of the peace-offering" (Leviticus 7:37). I only know this in general, so where do we derive this in detail? "This is the Torah of the burnt-offering" (Leviticus 6:2), "This is the Torah of the grain-offering" (Leviticus 6:7), "This is the Torah of the sin-offering" (Leviticus 6:18), "This is the Torah of the guilt-offering" (Leviticus 7:1), "This is the Torah of the peace-offering" (Leviticus 7:11). I only know this for individual sacrifices, so where do we derive this for communal sacrifices? The verse (Numbers 29:39) says, "Do these for Adonai on your set times," but finishes with "your peace-offerings." I only know this in this world, so from where do we derive this in the next? "I will extend to her peace like a wadi" (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 the Lord said to him: Go through the midst of the city, through the midst of Jerusalem, and set a mark [tav] upon the foreheads of the men that sigh and that cry on account of all the abominations that are done in her midst” (Ezekiel 9:4). The Holy One, Blessed be He, said to the angel Gabriel: Go and inscribe a tav of ink on the foreheads of the righteous as a sign so that the angels of destruction will not have dominion over them. And inscribe a tav of blood on the foreheads of the wicked as a sign so that the angels of destruction will have dominion over them...And what is different about the letter tav, that it was inscribed on the foreheads of the righteous? Rav said: Tav is the first letter of the word tiḥye, you shall live, indicating that the righteous shall live. Tav is also the first letter of the word tamut, you shall die, indicating that the wicked shall die. And Shmuel said: The letter tav is the first letter of the word tama, ceased, indicating that the merit of the Patriarchs has ceased and will not help the wicked. Rabbi Yoḥanan said: The letter tav is the first letter of the word taḥon, will have mercy, indicating that due to the merit of the Patriarchs God will have mercy on the righteous. And Reish Lakish said: The letter tav is the last letter of the seal of the Holy One, Blessed be He, as Rabbi Ḥanina said: The seal of the Holy One, Blessed be He, is truth [emet], which ends with the letter tav

It was taught in the Tosefta: There is no greeting [shalom] others permitted in the bathhouse. The Gemara comments that this statement supports the opinion of Rav Hamnuna in the name of Ulla, who said: It is forbidden for a person to greet [shalom] his friend in the bathhouse because Shalom is one of the names of God, as it is stated: “And Gideon built there an altar for God and he called Him Lord Shalom” (Judges 6:24). Therefore, it is prohibited to utter the word shalom in a dishonorable place.
