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. 18 Seek advice from every wise person and do not despise any useful counsel. 19 At all times bless the Lord God, and ask him that your ways may be made straight and that all your paths and plans may prosper. For none of the nations has understanding, but the Lord himself will give them good counsel; but if he chooses otherwise, he casts down to deepest Hades. So now, my child, remember these commandments, and do not let them be erased from your heart.
Shabbat 31a
Babylonian TalmudThere was another incident involving one gentile who came before Shammai and said to Shammai: Convert me on condition that you teach me the entire Torah while I am standing on one foot. Shammai pushed him away with the builder’s cubit in his hand. This was a common measuring stick and Shammai was a builder by trade. The same gentile came before Hillel. He converted him and said to him: That which is hateful to you do not do to another; that is the entire Torah, and the rest is its interpretation. Go study.
Notes and References
"... The rabbis of the Talmud were not the only ones to adopt “love your neighbor as yourself” as a cardinal principle and then interpret it to make it more practical. We find in Christian Scriptures (Luke 6:31, Matthew 7:12) attributed to Jesus what came to be later known as the Golden Rule ... “do unto others as you would have them do unto you.” It is clear that the source for this Rule is our verse in Leviticus (see also Matthew 22:37-40). The Christian formulation is a positive one, namely, do unto others ... while the Jewish one is a negative interpretation, don’t do unto others ... One might suggest that Hillel, who interpreted the verse in a negative manner, did so because he was dealing with a potential convert and didn’t want to alienate him from Judaism by making it appear too difficult. By rendering “love your neighbor as yourself” in the way Hillel did, the gentile, who likely came from a pagan background with little emphasis on universal ethical values, would find it easier to cleave to the Jewish religion. Hillel’s interest in promoting conversion is clearly evident from some of the other stories that appear on the same Talmudic page as the one-legged seeker story. (Shabbat 31a) But this hypothesis is negated by a verse in the apocryphal Book of Tobit (4:15-16) wherein we have again the negative formulation of “love your neighbor as yourself” standing in for the Biblical verse. Hillel’s reformulation is thus not unique to him but is rather an adoption of what appears to be an older Jewish interpretive tradition ..."
