Gospel of Luke:
“I tell you who hear me, love your enemies, do good to those who hate you, bless those who curse you, pray for those who mistreat you, do to others as you would have them do to you. If you love those who love you, what credit is that? Even sinners love those who love them.”
"Give and it shall be given to you, from the measures you use it will be measured to you. "
