If a person of learning participates in public affairs and serves as judge or arbiter, he gives stability to the land... But if he sits in his home and says to himself, “What have the affairs of society to do with me?... Why should I trouble myself with the people’s voices of protest? Let my soul dwell in peace!”—if he does this, he overthrows the world. [translation by Hazon]

There are four types of charity givers. One who wishes to give, but that others should not give: their eye is evil towards that which belongs to others; One who wishes that others should give, but that they themselves should not give: their eye is evil towards that which is their own; One who desires that they themselves should give, and that others should give: they are pious; One who desires that they themselves should not give and that others too should not give: they are wicked.

Ben ‘Azzai said: “'This is the book of the descendants of Adam' is a great principle of the Torah.” R. Akiva said: "'Love your neighbor as yourself' (Leviticus 19:18) is a great principle, so that you must not say, "Since I have been put to shame, let my neighbor be put to shame, since I have been cursed, let my neighbor be cursed." R. Tanhuma said: "If you do so, know whom you put to shame, for 'In the image of God did God make him'" (Genesis 5:1).

As long as one is but an ordinary scholar, he has no concern with the congregation and is not punished [for its lapses], but as soon as he is appointed head and dons the cloak [of leadership], he must no longer say: ‘I live for my own benefit, I care not about the congregation,’ but the whole burden of the community is on his shoulders. If he sees a man causing suffering to another, or transgressing, and does not prevent him, then he is held punishable. The Holy Spirit then exclaims, ‘My son, if you have become surety for your neighbor’- you are responsible for him, because ‘you have shaken hands on behalf of a stranger’” (Proverbs 6:1). The Holy Blessed One says to him: “‘You [by assuming office] have placed yourself in the arena’, and he who places himself in the arena stands either to fail or win. We two stand in the arena; either you prevail or I.” [Soncino translation]

Rabbi Tarfon and some elders were reclining in an upper chamber in the house of Nitza in Lod when this question came up: Which is greater, study or action? Rabbi Tarfon spoke up and said: Action is greater. Rabbi Akiva spoke up and said: Study is greater. The others then spoke up and said: Study is greater because it leads to action.

Our Rabbis have taught: A man should always be gentle as the reed and never unyielding as the cedar. Once R. Eleazar son of R. Simeon was coming from Migdal Gedor, from the house of his teacher, and he was riding leisurely on his donkey by the riverside and was feeling happy and elated because he had studied much Torah.

There chanced to meet him an exceedingly ugly man who greeted him, ‘Peace be upon you, Sir’. He, however, did not return his salutation but instead said to him, ‘Reika (Worthless!), how ugly you are. Are all your fellow citizens as ugly as you are?’ The man replied: ‘I do not know, but go and tell the craftsman who made me, "How Ugly is the vessel which you have made".’ When R. Eleazar realized that he had done wrong he dismounted from the donkey and prostrated himself before the man and said to him, ‘I submit myself to you, forgive me’. The man replied: ‘I will not forgive you until you go to the craftsman who made me and say to him,"How ugly is the vessel which you have made".’ He [R. Eleazar] walked behind him until he reached his native city. When his fellow citizens came out to meet him greeting him with the words, ‘Peace be upon you O Teacher, O Master,’ the man asked them, ‘Whom are you addressing thus’? They replied, ‘The man who is walking behind you.’ Thereupon he exclaimed: ‘If this man is a teacher, may there not be any more like him in Israel’! The people then asked him: ‘Why’? He replied: ‘Such and such a thing has he done to me. They said to him: ‘Nevertheless, forgive him, for he is a man greatly learned in the Torah.’ The man replied: ‘For your sakes I will forgive him, but only on the condition that he does not act in the same manner in the future.’ Soon after this R. Eleazar son of R. Simeon entered [the Beit Hamidrash] and expounded thus, A man should always be gentle as the reed and let him never be unyielding as the cedar. And for this reason the reed merited that of it should be made a pen for the writing of the Law, Tefillin and Mezuzot. [Soncino translation]
