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.

Tosefta Bava Kamma 9

He who injures his fellow, even though the one who did the injury did not seek forgiveness from the injured party - the injured party nonetheless has to seek mercy for him, since it says, "Then Abraham prayed to God, and God healed Abimelech." And so you find in regard to the friends of Job, as it said, "Now, therefore take seven bulls and seven rams and go to my servant Job, and offer yourselves up a burnt offering; and my servant Job shall pray for you."

Rabbi Judah says in the name of Rabban Gamaliel, "Lo, it says, '...and show you mercy and have compassion on you, and multiply you..." Let this sign be in your hand, "So long as you are merciful, He will have mercy on you."
