A Torah Sage should not shout or shriek while speaking, like the cattle and wild beasts, nor should he raise his voice overly much. Instead, he should speak gently to all people. [In addition to] speaking gently, he should take care not to stand at a distance, lest [his speech] appear like the speech of the haughty.
He should greet all men [before they greet him], so that they be pleased with him. He should judge every one in a good light, speak favorably of his fellow man, [never mentioning] anything that is shameful to him, love peace and pursue it.
If he sees that his words will be effective, and will be given attention, he should speak; if not, he should keep silent. What is implied? He should not try to placate a man in the moment of his anger. He should not question a man about his vow at the time he is making his vow, [but wait] until he is tranquil of mind and calm. He should not comfort a man while his dead is lying before him because [the bereaved] is unsettled until he has buried [his dead]. The same applies in other similar cases. He should not look at his fellow man at the moment of his humiliation, but turn his attention away.
He should not distort facts, exaggerate a situation, or minimize it, except in the interests of peace and the like.
The guiding rule is that he should speak only words of wisdom or in connection with acts of kindness and the like. He should not speak to a woman in the marketplace, even if she be his wife, or his sister, or his daughter.
