Loving Your Neighbor as Yourself: What Did the Rabbis Say?

You shall neither take vengeance nor bear a grudge against members of your people.
Love your neighbor as yourself:

I am The LORD.

...Another incident involving one gentile who came before Shammai (50 BCE – 30 CE) and said to Shammai: "Convert me on condition that you teach me the entire Torah while I am standing on one foot."
He pushed him away with the builder’s cubit in his hand.
He came before Hillel (d. 10 CE). 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."

"And you shall love your neighbor as yourself":

Rabbi Akiva (50-135 CE) says: "This is an all-embracing principle in the Torah."

Ben Azzai (first third of the 2nd century) says: "'This is the numeration of the generations of Adam' (Gen. 5:1) — This is an even greater principle."

Rav Yehudah (220–299 CE) said: "Rav (175–247 CE) said: 'It is forbidden for a man to betroth a woman until he sees her, lest he see something repulsive in her and she will become repugnant to him, and the Merciful One states “And you shall love your neighbor as yourself” (Leviticus 19:18).'"

A dilemma was raised before the Sages: What is whether a son may let blood for his father?
Rav Mattana (250-290 CE) said: "'And you shall love your neighbor as yourself' (Leviticus 19:18)."

Rav Dimi bar Ḥinnana said: "One who strikes a person and one who strikes an animal: Just as one who strikes an animal for medical purposes is exempt from paying restitution, so too, one who strikes a person for medical purposes is exempt from liability."

Rav Ḥisda (228-320 CE) said: "It is prohibited for a person to engage in intercourse by day, as it is stated: 'And you shall love your fellow as yourself' (Leviticus 19:18)."

From where is this inferred?

Abaye (280-337 CE) said: "Perhaps he will see some repulsive matter and she will become repugnant to him."

Rav Huna (216-297 CE) said: "Jews are holy, and they do not engage in intercourse by day."
Rava (280-352 CE) said: "And if the house is dark, it is permitted. And in the case of a Torah scholar, he may cause darkness with his garment and engage in intercourse."

Rav Naḥman (d. 320 CE) said: "Rabbah bar Avuh (250-290 CE) said: 'The verse states: “And you shall love your neighbor as yourself” (Leviticus 19:18) -select a good, i.e., a compassionate, death for him."

There, they say: “A man is stoned naked but no woman is stoned naked.” And here, they say so? There, “you shall love your neighbor as yourself,” choose for him the easiest death. But here, “all women should be taught and not do as your whoring.”

There, they say: “A man is stoned naked, but no woman is stoned naked.” And here, they say so? Here, you shall love your neighbor as yourself, choose for him a decorous death. But here, all women should be taught.
