Tzedaka (Charity) and Gemilut Chesed (Acts of Kindness)
(ח) וַיֹּ֥אמֶר קַ֖יִן אֶל־הֶ֣בֶל אָחִ֑יו וַֽיְהִי֙ בִּהְיוֹתָ֣ם בַּשָּׂדֶ֔ה וַיָּ֥קָם קַ֛יִן אֶל־הֶ֥בֶל אָחִ֖יו וַיַּהַרְגֵֽהוּ׃ (ט) וַיֹּ֤אמֶר יְהוָה֙ אֶל־קַ֔יִן אֵ֖י הֶ֣בֶל אָחִ֑יךָ וַיֹּ֙אמֶר֙ לֹ֣א יָדַ֔עְתִּי הֲשֹׁמֵ֥ר אָחִ֖י אָנֹֽכִי׃ (י) וַיֹּ֖אמֶר מֶ֣ה עָשִׂ֑יתָ ק֚וֹל דְּמֵ֣י אָחִ֔יךָ צֹעֲקִ֥ים אֵלַ֖י מִן־הָֽאֲדָמָֽה׃
(8) Cain said to his brother Abel … and when they were in the field, Cain set upon his brother Abel and killed him. (9) The LORD said to Cain, “Where is your brother Abel?” And he said, “I do not know. Am I my brother’s keeper?” (10) Then He said, “What have you done? Hark, your brother’s blood cries out to Me from the ground!

(ב) וְכָל הָרוֹאֶה עָנִי מְבַקֵּשׁ וְהֶעֱלִים עֵינָיו מִמֶּנּוּ וְלֹא נָתַן לוֹ צְדָקָה עָבַר בְּלֹא תַּעֲשֶׂה שֶׁנֶּאֱמַר (דברים טו ז) "לֹא תְאַמֵּץ אֶת לְבָבְךָ וְלֹא תִקְפֹּץ אֶת יָדְךָ מֵאָחִיךָ הָאֶבְיוֹן":

(2) 2. Anyone who deliberately ignores a beggar and does not give to him commits a sin as it says "Thou shalt not strengthen thy heart nor tighten thy hand against your poor brother."

(נחום א, יב) ועניתיך אמר מר זוטרא אפי' עני המתפרנס מן הצדקה יעשה צדקה לא אענך עוד תני רב יוסף שוב אין מראין לו סימני עניות:
The Gemara addresses the continuation of the verse: “And though I have afflicted you [ve’innitikh]” (Nahum 1:12). Mar Zutra says: This means that even a poor person [ani] who is sustained from charity must also perform charity. With regard to the expression: “And I will afflict you [a’anekh] no more,” Rav Yosef teaches: This means that if he gives charity to others, God will no longer show him signs of poverty [aniyyut].
ת"ר יתום ויתומה שבאו להתפרנס מפרנסין את היתומה ואחר כך מפרנסין את היתום מפני שהאיש דרכו לחזור על הפתחים ואין אשה דרכה לחזור יתום ויתומה
The Sages taught: Concerning an orphan boy and an orphan girl who have come and appealed to be supported by the charity fund, the distributors provide for the orphan girl first and afterward they provide for the orphan boy. This is because it is the way of a man to circulate about the entryways to ask for charity, and it is not a woman’s way to circulate for charity. Therefore, her need is greater. Concerning an orphan boy and orphan girl
שבאו לינשא משיאין את היתומה ואחר כך משיאין את היתום מפני שבושתה של אשה מרובה משל איש:
who have come to appeal to the charity fund to be married off, the administrators marry off the orphan girl first and afterward they marry off the orphan boy, because the humiliation of a woman who is not married is greater than that of an unmarried man.

Rabbi Shmelke of Nicholsburg
When a poor man asks you for aid, do not use his faults as an excuse for not helping him. For then God will look for your offenses, and He is sure to find many of them. Keep in mind that the poor man's transgressions have been atoned for by his poverty while yours still remain with you.
From Unzer Alter Otzer, II, p. 99

Rabbi Chayim of Sanz

The merit of charity is so great that I am happy to give to 100 beggars even if only one might actually be needy. Some people, however, act as if they are exempt from giving charity to 100 beggars in the event that one might be a fraud.
Darkai Chayim (1962),p. 137

ת"ר מפרנסים עניי נכרים עם עניי ישראל ומבקרין חולי נכרים עם חולי ישראל וקוברין מתי נכרים עם מתי ישראל מפני דרכי שלום:

Similarly, the Sages taught in a baraita (Tosefta 5:4): One sustains poor gentiles along with poor Jews, and one visits sick gentiles along with sick Jews, and one buries dead gentiles along with dead Jews. All this is done on account of the ways of peace, to foster peaceful relations between Jews and gentiles.

(7) There are eight levels of charity, one above the other. The greatest level that has nothing above it is to strengthen the hand of a Jew who has become poor and give him a gift or loan or create a partnership with him or make up some work for him, so as strengthen his hand until he does not [any longer] need to ask others [for help]. And about this it is said (Leviticus 25:35), "and you shall strengthen the hand of a stranger and a resident and he shall live with you;" meaning, strenghten him until he no [longer] falls and becomes needy.

(8) Lower than that is when one gives charity to the poor and does not know to whom he is giving, and the poor person does not know from whom he is taking - since, behold, this is [performance of] the commandment for its own sake. Like this was the secret chamber which was in the Temple, to which the righteous would give secretly and from which the poor of the wealthy families would support themselves secretly. And approaching this is the one that gives to the charity box. And a person should not give to the charity box, unless he knows that the one in charge of it is trustworthy and wise and knows how to manage it appropriately, like [was the case with] Rabbi Chananya ben Tradyon.

(9) Lower than that is when the giver knows to whom he is giving, but the poor person does not know from whom he is taking. An example of this were the greatest of the Sages who would secretly go and place the money at the entrances of the [homes of the] poor. And it is fitting to do like this. And it is a good level when the charity managers are not behaving appropriately.

(10) Lower than that is when the poor person knows from whom he took and the giver does not know. An example of this were the greatest of the Sages who would bundle money in their sheets and lower them behind them and [then] the poor would come and take [the money], so that they would not feel embarrassment.

(11) Lower than that is when one gives it to him in his hand before he asks.

(12) Lower than that is when he gives it to him after he asks.

(13) Lower than that is when he gives him less than what is fit, [but] with a pleasant demeanor.

(14) Lower than that is when he gives it to him sadly.

(א) מִצְוַת עֲשֵׂה שֶׁל דִּבְרֵיהֶם לְבַקֵּר חוֹלִים. וּלְנַחֵם אֲבֵלִים. וּלְהוֹצִיא הַמֵּת. וּלְהַכְנִיס הַכַּלָּה. וּלְלַוּוֹת הָאוֹרְחִים. וּלְהִתְעַסֵּק בְּכָל צָרְכֵי הַקְּבוּרָה. לָשֵׂאת עַל הַכָּתֵף. וְלֵילֵךְ לְפָנָיו וְלִסְפֹּד וְלַחְפֹּר וְלִקְבֹּר. וְכֵן לְשַׂמֵּחַ הַכַּלָּה וְהֶחָתָן. וּלְסַעֲדָם בְּכָל צָרְכֵיהֶם. וְאֵלּוּ הֵן גְּמִילוּת חֲסָדִים שֶׁבְּגוּפוֹ שֶׁאֵין לָהֶם שִׁעוּר. אַף עַל פִּי שֶׁכָּל מִצְוֹת אֵלּוּ מִדִּבְרֵיהֶם הֲרֵי הֵן בִּכְלַל (ויקרא יט יח) "וְאָהַבְתָּ לְרֵעֲךָ כָּמוֹךָ". כָּל הַדְּבָרִים שֶׁאַתָּה רוֹצֶה שֶׁיַּעֲשׂוּ אוֹתָם לְךָ אֲחֵרִים. עֲשֵׂה אַתָּה אוֹתָן לְאָחִיךְ בְּתוֹרָה וּבְמִצְוֹת:

(1) It is a positive commandment to visit the sick, comfort the mourning, to remove the dead, to bring in the bride, to escort guests, and to occupy oneself with all the needs of burial; carrying [the coffin] on one’s shoulder, to walk in front of him, to eulogize, to dig, and to bury. As well to make the bride and groom happy, and to take care of all their needs. And these are ‘Gemillut Chasadim’ that are done with one’s body, that have no measurement. Although all these are rabbinic laws they are included under "Love Your neighbor as yourself" (Leviticus 19:18), meaning that all things that you would like others to do for you, you should do for your brother.

Rabbi Yisrael Meir Kagan (“Chofetz Chaim” [1838-1933, Poland])
On joyous occasions, such as at a marriage, people need others to join in their celebration – a celebration conducted in solitude is hardly joyous. Alternatively, when a person is depressed, or grieving over a loss, he greatly appreciates other people’s comforting words, which can effectively prevent him from lapsing into severe depression and illness.

(א) ללכת בכל דרכיו - אלו דרכי הקב"ה, שנ' (שמות לד) ה' ה' אל רחום וחנון, ארץ אפים ורב חסד ואמת, נוצר חסד לאלפים, נושא עון ופשע וחטאה ונקה. ואו' (יואל ג) כל אשר יקרא בשם ה' ימלט. וכי היאך אפשר לו לאדם להיקרא בשמו של הקב"ה? אלא מה המקום נקרא רחום וחנון - אף אתה הוי רחום וחנון ועשה מתנת חנם לכל. מה הקב"ה נקרא צדיק, שנ' (תהלים קמה) צדיק ה' בכל דרכיו וחסיד בכל מעשיו - אף אתה הוי צדיק. הקב"ה נקרא חסיד, שנאמ' וחסיד בכל מעשיו - אף אתה הוי חסיד; לכך נאמר כל אשר יקרא בשם ה' ימלט, ואומר (ישעיה מג) כל הנקרא בשמי ולכבודי בראתיו, יצרתיו אף עשיתיו, ואו' (משלי טז) כל פעל ה' למענהו:

(1) (Devarim 11:22) "to walk in His ways": Which are the ways of the Holy One Blessed be He? (Shemoth 34:6-7) "The L-rd, the L-rd, G-d of mercy and grace, slow to wrath and abundant in mercy and truth, keeping lovingkindness for thousands, forgiving transgression, offense, and sin, and cleansing …" And it is written (Yoel 3:5) "All who will be called by the name of the L-rd will escape": Now how is it possible for a man to be called by the name of the Holy One Blessed be He? But, (the intent is) just as the L-rd is called "merciful and gracious," you, too, be merciful and gracious, and give gratuitously to all. Just as the Holy One Blessed be He is called "righteous," viz. (Psalms 145:17) "Righteous is the L-rd in all His ways and saintly in all His acts" — you, too, be righteous. Just as the Holy One Blessed be He is called "saintly," — you, too, be saintly. This is the intent of "All who will be called by the name of the L-rd will escape." And it is written (Isaiah 43:7) "… everyone that is called by My name. For My honor I have created him, and formed him, and fashioned him." And it is written (Proverbs 16:4) "The L-rd has created all for His sake." (Devarim, Ibid.)

(2) We should be careful to not feel pained by giving tzedaka to the poor, nor should we give stingily, nor think of it as below us. Rather this should be in our eyes a merit, a benefit and an addition to his income, since God, Blessed be He, will compensate us in multiple ways......

(יב) ידעתי . ואני הנה השכלתי לדעת דרכי העולם ותועלותיו והן ידעתי שאין טוב ומאושר בבני אדם , כי אם מי שדרכו לשמוח ולעשות טוב חסד וצדקה בעוד שהוא חי :

(12) I know (because) I have studied the ways of the world and what is beneficial, that there is no person that is better or more praiseworthy among people than one whose way is to be happy and to do good, kindness and Tzedaka while he is alive.
