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.
Bava Kamma 93aBabylonian Talmud
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.

"... As a Christian becomes more familiar with the basic tenets of Judaism, many of Jesus's teachings will reveal their Jewish roots. There are dozens of examples in the Younger Testament that express the connection between Jesus's teachings and teachings recorded in later centuries that are part of the Oral Torah. As one more example (among many), when Jesus's opinion about healing on the Sabbath was in line with the emerging Jewish consensus of his day. Similarly, Jesus was a miracle worker in the tradition of Elijah and Elisha, and his teachings were in line with the powerful words of prophets ..."
