Halakhah su Genesi 18:19

And this is the intention of our rabbis z”l, when they say, “All who judge a judgement truthfully, it’s as if he is a partner with God in the creation of the world,” because God created the world to continue and the wicked who steal and commit acts of violence ruin the world through their actions. And similarly we find regarding the generation of the flood that the decree of their judgement was sealed only because of theft, as it is written, (Genesis 6:11) “For the earth is filled with violence,” and it says after this, (Genesis 6:13) “I will destroy them with the earth”. What emerges is that the judge who breaks the high arms of the wicked keeps the world going and completes the will of the Creator, blessed is His name, who created it to keep going, and it is as if they become partners with the Holy One ,Blessed Be He, in the creation. Abraham our forefather didn’t know God, and He called him (Isaiah 41:8) “My beloved” because he walked in the ways of justice and guided his children, as it is written, (Genesis 18:19) “For I have known him, to the end that he may command his children and his household after him, that they may keep the way of God, to do righteousness and justice…” And Moses our teacher a”h, master of all prophets, took advice from Yitro with regards to justice, to establish judges to caution Israel and to command them through justice, and God agreed with this. And Joshua afterwards established a covenant with Israel to serve God, he left his last word as justice, as it is written, (Joshua 24:25) “On that day Joshua made a covenant for the people, and there at Shechem he reaffirmed for them laws and justice.” [This is] because justice is the foundation and the great principle in the service of God, and following [Abraham] have each and every judge judged their generation, and bring them back from their evil ways to service of God to go in the way that Abraham paved to do righteousness and justice, and through this were they [i.e. the Jewish people] were saved from their enemies until Samuel the prophet came, God-faithful, (1 Samuel 7:15-16) “who judged Israel all the days of his life. And he went on a circuit year by year to Bethel, Gilgal, and Mizpah. And he judged Israel in all these places.” And our sages tell us that the path he took one year was not the one he took the next, so that he could turn the hearts of the entire nation toward service of God, and to walk in the way of Abraham our forefather a”h, and he anointed David to be the king of Israel, and he too walked in the ways of God from all that was in front of him, as it is written,(2 Samuel 8:15) “And David did justice and righteousness. (1 Chronicles 11:8) “And Joab restored the rest of the city.” And our sages tell us that in the merit of the justice and righteousness of David, Joab restored the rest of the city, and had his child [Solomon] continue after him, the “Yedid Hashem”, who loved to go in the laws of his father David and would ask from God an understanding, listening heart to judge his people, to understand between good and bad, and it was good in God’s eyes, that which he asked regarding this. And He gave him a wise and understanding heart which has never been before, and no one has been like him since, and all of Israel was afraid of him because they saw that the wisdom of God was in his heart to do justice. And also Jehoshaphat, who took the paths of his father and raised his heart in the ways of God, was strengthened in justice, and he appointed judges in every city, and he said to the judges, “See what you do, for you are not judging for man but for God, and with you shall be justice.” Josiah as well, that Scripture testifies about him, “And no king was like him before, who returned to God with all his heart.” And also the King Messiah, who will be revealed speedily in our days, is praised by Scripture regarding justice, and it is written, (Isaiah 11:4) “And he will judge the destitute with justice, and decide with equity for the meek of the earth…” And according to the greatness of his reward will be the punishment for those who void and pervert it, as it is taught, “Destruction comes to the word based on lack of law and on the perversion of law.” And so did David say, (Psalms 119:121) “I have done justice and righteousness, leave me not to my oppressors.” This implies that without justice, he would have been left in the hands off oppressors. And Jerusalem was only destroyed, and Israel only exiled, because of the neglecting of justice, as it is written, (Isaiah 1:21) “She once was full of justice; righteousness used to dwell in her-- but now murderers.”... And God wants it more than all the sacrifices, as it is written, “Doing righteousness and justice is choicier to God than the zevach offerings.” It does not says “than sin and burnt offerings,” but rather “than zevach offerings.”

From time immemorial, Judaism has manifested a concern for education bordering on the obsessive. Abraham is described as worthy of divine favor "For I have known him to the end that he may instruct his children and his household after him, that they keep the way of God, to do righteousness and justice" (Genesis 18:19). Loyalty to the traditions of Judaism in adulthood can be assured only if proper training is provided during formative years. As expressed by King Solomon, "Train a child in his way and even when he is old he will not depart from it" (Proverbs 22:6).

Rav Yechiel Michel Tukachinsky, in his classic work Gesher Hachaim (1:41), writes that everyone should write an ethical will in addition to the standard will concerning his assets. As a source for this practice, he cites the celebrated pasuk (Bereishit 18:19) that states that Hashem considered Avraham special “because he commands his children and his household after him that they keep the way of Hashem, doing charity and justice.” Moreover, the Ralbag (I Melachim 2:46) writes that everyone should learn from the example set by Moshe Rabbeinu, Yehoshua, and David Hamelech (we may add Yosef Hatzadik to the list), all of whom presented ethical wills before they died. There is a long tradition among great rabbis, including the Vilna Gaon, Rav Aryeh Levine, and Rav Shlomo Wolbe, to follow the example set by these biblical figures.

It is a positive commandment to give charity to poor Jewish people, as it is said "Open your hand to him."¹Deuteronomy 15:8. And it is said: "That your brother may live with you."²Leviticus 25:36. Anyone who sees a poor person seeking help and ignores him, and does not give him charity, transgresses a prohibitive commandment, as it is said: "Do not harden your heart nor shut your hand from your brother in need."³Numbers 15:7. [Giving] charity is a characteristic of the descendants of Abraham, as it is said: "For I have a special love for him because he commands his children and his household after him [to preserve the way of Hashem] doing charity and justice."⁴Genesis 18:19. And the throne of Israel will be established and the religion of truth confirmed only through charity, as it is said: "Through charity will you be reestablished."⁵Isaiah 54:14. Greater is he who performs acts of charity than [one who brings] all the sacrifices, as it is said: "Performing acts of charity and justice is more desirable to Hashem than sacrifices."⁶Proverbs 21:3. The Jewish people will be redeemed only through [the merit of] charity, as it is said: "Zion will be redeemed through justice and its captives through acts of charity."⁷Isaiah 1:27. A person never becomes poor through giving charity, nor will any evil or harm befall him because of his giving charity, as it is said: Through acts of charity, there will be peace."⁸Isaiah 32:17. Whoever is merciful with others will be treated with mercy [from Heaven], as it is said: "He [God] will show you mercy; and have compassion upon you and multiply you."⁹Deuteronomy 13:18. Anyone who is cruel, causes his lineage to be suspect.¹⁰The descendants of Abraham are known for their kindness and generosity. One who does not possess this attitude causes his lineage to be doubtful. The Holy One blessed is He, is near to the cry of the poor, as it is said: "He will hear the cry of the poor."¹¹Job 34:28. Therefore one must beware of their anguished cry, for a covenant was made with them, as it is said: "When he cries out to me I will listen, for I am compassionate."¹²Exodus 22:26. The Jerusalem Talmud says: The door that doesn't open for the poor will open for the doctor. A person should consider, that he continually requests his sustenance from the Holy One blessed is He; and just as he requests that the Holy One blessed is He, listen to his cry and prayer, so should he listen to the cry of the poor. A person should also consider that [fortune] is a wheel that revolves in the world, and in the end he or his children or his children's children might [have to] accept charity. Let no man think: "Why should I diminish my wealth by giving it to the poor?" For he should know that the money is not his, but rather [it was given to him as] a trust, with which to do the will of the One Who entrusted the funds to him. And this [charity giving] will be his real share from all his toils in this world, As it is written:¹³Isaiah 58:8. "Your acts of charity shall preceed you [into the World to Come]. Charity voids evil decrees and prolongs life.
