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. 10Blessed 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.

The Gemara provides another lesson from the story of Abraham and Abimelech. And Rabbi Yitzḥak says: The curse of an ordinary person should never be regarded as light in your eyes, for Abimelech cursed Sarah and it was fulfilled in her descendant. The curse on Sarah is as it is stated: “Behold, it is to you a covering of the eyes” (Genesis 20:16), meaning that he said to her: Since you concealed your status from me and you did not reveal that Abraham is your husband, and you caused me this suffering, may it be God’s will that you should have children with covered eyes. And this curse was fulfilled in her descendant, as it is written: “And it came to pass, that when Isaac was old, and his eyes were dim, so that he could not see” (Genesis 27:1). Rabbi Abbahu says: A person should always be among those who are pursued and not among the pursuers. One can prove that this is so, as none among birds are pursued more than doves and pigeons, as all predators hunt them, and from all birds the verse deemed them fit to be sacrificed on the altar.
