Yet another segulah for parnassah is to be generous with one's money.
This week's parashah discusses the mitzvah of providing loans, as it states (15:8) לו יחסר אשר מחסרו די תעביטנו והעבט, "You shall lend him sufficient for his needs, which he is lacking."
The Chinuch (480) writes, "The purpose of this mitzvah is to establish the attribute of generosity in our hearts and to distance us as far as possible from stinginess. Anyone familiar with the Torah's paths and comprehends its beautiful ways knows with certainty that when he is generous with his money, he will gain more. And whoever refrains will lose. This is because Hashem acts with people according to their deeds. Being stingy with money erects an iron wall that separates the person from Hashem's brachos. Generosity is, in itself, a blessing; therefore, those who act with kindness receive blessings."
The Avodas Yisrael teaches that when Hashem wants to give kindness to someone, and the person doesn't deserve it, Hashem will arrange that this person should perform kindness to others. This makes him a worthy candidate to receive Hashem's blessings. This is implied in the words (Shemos 33:19) אחון אשר וחנותי, "I will favor whom I wish to favor." This can be translated as וחנותי, I will grant him the opportunity to have compassion on others so that Hashem can have mercy on him.
דמים means blood, and it also means money. Sefer HaChaim (Parnassah v'Kalkalah written by the Maharal's brother) explains that one gives blood to receive blood. (He is referring to דם הקזת, blood-letting, which is a form of refuah. He gives his blood so he will remain alive and have blood.) Sefer HaChaim says that the same is true with money. One gives money so that he can have money. When he is generous with his money, Hashem will give him more.
It states (Vayikra 19:9) שדך פאת תכלה לא. This can be translated as, "Don’t cause that your field should become a wasteland and destroyed." Sefer HaChaim explains that if you don't give part of your crops to the poor (ופאה שכחה לקט), he is destroying his field. He thinks he is protecting his produce by keeping it to himself, but he is destroying everything he has because only by being generous with others will his wealth remain with him.
Sefer HaChaim adds, "Just as you should teach your children the path of emunah, so should you also teach them the path of tzedakah. As Hashem said to Avraham (Breishis 18:19) אחריו ביתו ואת בניו את יצוה אשר למען צדקה לעשות 'ה דרך ושמרו, 'For I love him because he commands his sons and his household after him, that they should keep the way of Hashem to perform tzedakah...'
