New Testament

Matthew 5:1-16

1 When he saw the crowds, he went up the mountain. After he sat down his disciples came to him. 2 Then he began to teach them by saying:
3 “Blessed are the poor in spirit, for the kingdom of heaven belongs to them.
4 Blessed are those who mourn, for they will be comforted.
5 Blessed are the meek, for they will inherit the earth.
6 Blessed are those who hunger and thirst for righteousness, for they will be satisfied.
7 Blessed are the merciful, for they will be shown mercy.
8 Blessed are the pure in heart, for they will see God.
9 Blessed are the peacemakers, for they will be called the children of God.
10 Blessed are those who are persecuted for righteousness, for the kingdom of heaven belongs to them.
11 Blessed are you when people insult you and persecute you and say all kinds of evil things about you falsely on account of me. 12 Rejoice and be glad because your reward is great in heaven, for they persecuted the prophets before you in the same way.

13 “You are the salt of the earth. But if salt loses its flavor, how can it be made salty again? It is no longer good for anything except to be thrown out and trampled on by people! 14 You are the light of the world. A city located on a hill cannot be hidden. 15 People do not light a lamp and put it under a basket but on a lampstand, and it gives light to all in the house. 16 In the same way, let your light shine before people, so that they can see your good deeds and give honor to your Father in heaven.

Pirkei Avot 1:8-13

8 Judah ben Tabbai and Shimon ben Shetach received [the oral tradition] from them. Judah ben Tabbai said: do not [as a judge] play the part of an advocate; and when the litigants are standing before you, look upon them as if they were [both] guilty; and when they leave your presence, look upon them as if they were [both] innocent, when they have accepted the judgement.

9 Shimon ben Shetach used to say: be thorough in the interrogation of witnesses, and be careful with your words, lest from them they learn to lie.

10 Shemaiah and Abtalion received [the oral tradition] from them. Shemaiah used to say: love work, hate acting the superior, and do not attempt to draw near to the ruling authority.

11 Abtalion used to say: Sages be careful with your words, lest you incur the penalty of exile, and be carried off to a place of evil waters, and the disciples who follow you drink and die, and thus the name of heaven becomes profaned.

12 Hillel and Shammai received [the oral tradition] from them. Hillel used to say: be of the disciples of Aaron, loving peace and pursuing peace, loving mankind and drawing them close to the Torah.

13 He [also] used to say: one who makes his name great causes his name to be destroyed; one who does not add [to his knowledge] causes [it] to cease; one who does not study [the Torah] deserves death; one who makes [unworthy] use of the crown [of learning] shall pass away.
