These are the precepts that have no prescribed measure: the corner of a field [which must be left for the poor], the first fruit offering, the pilgrimage [to the Temple Mount], acts of kindness, and Torah study.Mishna, Peah 1:1
These are the precepts whose fruits a person enjoys in This World but whose
principal remains intact for him in the World to Come. They are: the honor due to father
and mother, acts of kindness, early attendance at the house of study morning and
evening, hospitality to guests, visiting the sick, providing for a bride, escorting the
dead, absorption in prayer, bringing peace between man and his fellow, and the study of
Torah is equivalent to them all. Talmud, Shabbat 127a
Do not harden your heart or shut your hand against your needy brother... I am commanding you to open your hand generously to your poor and destitute brother in your land.Dvarim (Deuteronomy) 15:7-11
After Abraham died, G-d blessed Isaac, his son.Bereshit (Genesis) 25:11
Constitutes a great Mitzvah to visit a mourner, to comfort and to enable him/her to express grief. When leaving a house of mourning, it is traditional for the guest to say, "HaMakom Yenachem Otcha (Etchem) BeToch Shear Avelei Tzion veYerushalaim" ("May the Lord comfort you with all the mourners of Zion and Jerusalem").
Do not go around as a gossiper among your people.Vayikra (Leviticus) 19:16
Whoever shames his neighbor in front of others, has no portion in the World to Come.
Talmud, Baba Metzia 58b
When you build [or buy or rent] a new house, you must place a guard-rail around your roof. Do not allow a dangerous situation to remain in your house, since someone can fall from [an unenclosed roof].Dvarim (Deuteronomy) 22:8
