27 “But I say to you who are listening: Love your enemies, do good to those who hate you, 28 bless those who curse you, pray for those who mistreat you. 29 To the person who strikes you on the cheek, offer the other as well, and from the person who takes away your coat, do not withhold your tunic either. 30 Give to everyone who asks you, and do not ask for your possessions back from the person who takes them away. 31 Treat others in the same way that you would want them to treat you. 32 “If you love those who love you, what credit is that to you? For even sinners love those who love them. 33 And if you do good to those who do good to you, what credit is that to you? Even sinners do the same. 34 And if you lend to those from whom you hope to be repaid, what credit is that to you? Even sinners lend to sinners, so that they may be repaid in full. 35 But love your enemies, and do good, and lend, expecting nothing back. Then your reward will be great, and you will be sons of the Most High, because he is kind to ungrateful and evil people. 36 Be merciful, just as your Father is merciful.
(Devarim 11:22) "to walk in His ways": Which are the ways of the Holy One Blessed be He? (Shemoth 34:6-7) "The L-rd, the L-rd, G-d of mercy and grace, slow to wrath and abundant in mercy and truth, keeping lovingkindness for thousands, forgiving transgression, offense, and sin, and cleansing …" And it is written (Yoel 3:5) "All who will be called by the name of the L-rd will escape": Now how is it possible for a man to be called by the name of the Holy One Blessed be He? But, (the intent is) just as the L-rd is called "merciful and gracious," you, too, be merciful and gracious, and give gratuitously to all. Just as the Holy One Blessed be He is called "righteous," viz. (Psalms 145:17) "Righteous is the L-rd in all His ways and saintly in all His acts" — you, too, be righteous. Just as the Holy One Blessed be He is called "saintly," — you, too, be saintly. This is the intent of "All who will be called by the name of the L-rd will escape." And it is written (Isaiah 43:7) "… everyone that is called by My name. For My honor I have created him, and formed him, and fashioned him." And it is written (Proverbs 16:4) "The L-rd has created all for His sake." (Devarim, Ibid.)
