12 and forgive us our debts, as we ourselves have forgiven our debtors. 13 And do not lead us into temptation, but deliver us from the evil one. 14 “For if you forgive others their sins, your heavenly Father will also forgive you. 15 But if you do not forgive others, your Father will not forgive you your sins. 16 “When you fast, do not look sullen like the hypocrites, for they make their faces unattractive so that people will see them fasting. I tell you the truth, they have their reward!

In a similar vein, the Gemara relates that Rabbi Ḥiyya said to his wife: When a poor person comes to the house, be quick to give him bread so that they will be quick to give bread to your children. She said to him: Are you cursing them, your children? He said to her: It is a verse that is written, as it says: “Due to this thing,” and the school of Rabbi Yishmael taught that it is a wheel that continuously turns in the world. Similarly, it was taught in a baraita that Rabbi Gamliel, son of Rabbi Yehuda HaNasi, says: The verse that states: “And He will show you mercy and have compassion on you and multiply you” (Deuteronomy 13:18) teaches us that anyone who has compassion for God’s creatures will receive compassion from Heaven, and anyone who does not have compassion for God’s creatures will not receive compassion from Heaven.
