Busting the Myth of "The Giving Tree"

The Gemara asks: And Rabbi Yoḥanan, what does he do with this verse: “And your brother shall live with you”? The Gemara answers: He requires the verse for that which is taught in a baraita: If two people were walking on a desolate path and there was a jug [kiton] of water in the possession of one of them, and the situation was such that if both drink from the jug, both will die, as there is not enough water, but if only one of them drinks, he will reach a settled area, there is a dispute as to the halakha. Ben Petora taught: It is preferable that both of them drink and die, and let neither one of them see the death of the other. This was the accepted opinion until Rabbi Akiva came and taught that the verse states: “And your brother shall live with you,” indicating that your life takes precedence over the life of the other.

You shall not take vengeance or bear a grudge against your countrymen. Love your fellow as yourself: I am the LORD.

(35) If your kinsman, being in straits, comes under your authority, and you hold him as though a resident alien, let him live by your side: (36) do not exact from him advance or accrued interest, but fear your God. Let him live by your side as your kinsman.

§ Apropos the ordinances instituted by the Sages in Usha, the Gemara cites another one. Rabbi Ile’a said: In Usha the Sages instituted that one who dispenses his money to charity should not dispense more than one-fifth. That opinion is also taught in a baraita: One who scatters should not scatter more than one-fifth, lest he render himself destitute and need the help of other people.

He [also] used to say: If I am not for myself, who is for me? But if I am for my own self [only], what am I? And if not now, when?
