Great is peace, for the prophets have taught all people to care for nothing so much as peace….

Great is peace, for it was given to the meek; as it says: But the lowly shall inherit the land, and delight themselves in abundance of peace” (Psalms 37:11).

Great is peace, for it outweighs everything. We say in the morning prayers: “He makes peace and creates everything.” Without peace, there is nothing.

Even if Israel serves idols and peace reigns among them, the Holy One, blessed be He, as it were, says: “Satan shall not touch them.”…

Peace is a grand thing and quarrelsomeness is hateful. Peace is a great thing, for even during war peace is necessary; as it says: “When you approach a town to attack it, you shall offer it in terms of peace” (Deuteronomy 20:10).…

Great is peace, for even the dying need peace; as it says: “You shall go to your fathers in peace” (Genesis 15:15), and it says: “You shall die in peace” (Jeremiah 34:5).…

Great is peace, for the Holy One has created no finer attribute than peace, and it has been given to the righteous. When a righteous man departs from the world three groups of ministering angels welcome him, each with a greeting of peace. The first says: “Yet he shall come in peace”; the second: “He shall have rest on his couch”; and the third, “So it is for each one who walked straightforward” (Isaiah 57:2).

Great is peace, for God is called Peace, as it says: “And he called the altar ‘The Lord is Peace'” (Judges 6:24).

Great is peace, for even the angels in heaven need peace, as it says: “He makes peace in his high places” (Job 25:2). Now, can we not reason from the less important to the more important? If peace is necessary in heaven, a place where there is no hatred or enmity, how much more so is it necessary on earth, where so many conflicts are found!
