Tobit 4:15
14 "Do not keep over until the next day the wages of those who work for you, but pay them at once. If you serve God you will receive payment. Watch yourself, my son, in everything you do, and discipline yourself in all your conduct. 15 And what you hate, do not do to anyone. Do not drink wine to excess or let drunkenness go with you on your way. 16 Give some of your food to the hungry, and some of your clothing to the naked. Give all your surplus as alms, and do not let your eye begrudge your giving of alms. 17 Place your bread on the grave of the righteous, but give none to sinners.
Matthew 7:12
7 “Ask and it will be given to you; seek and you will find; knock and the door will be opened for you. 8 For everyone who asks receives, and the one who seeks finds, and to the one who knocks, the door will be opened. 9 Is there anyone among you who, if his son asks for bread, will give him a stone? 10 Or if he asks for a fish, will give him a snake? 11 If you then, although you are evil, know how to give good gifts to your children, how much more will your Father in heaven give good gifts to those who ask him! 12 In everything, treat others as you would want them to treat you, for this fulfills the law and the prophets.
Notes and References
"... Although this maxim was found throughout the ancient world (see Moore 1996: 178–180), this most probably reflects the teachings of Hillel B. Shabb. 31a, who called this maxim the “whole Law.” [The Gospels] turns the phrase around to the positive, “Do to others as you would have them do to you.” The negative rendering means “avoid doing harm to others,” and that harm is defined by what you would not want done to you. The positive statement implies the active practice of good deeds, and those good deeds are defined as what you would want done to you ..."
