A good person will bequeath to grandchildren, but wealth of a sinner is secreted for a righeous person.
Proverbs 13:22
What does "wealth of a sinner is secreted for a righeous person" mean?
Here's Rashi's commentary for that verse, but the meaning of that phrase is still not clear to me:
A good man will leave an inheritance: of his merit and his property to his sons’ sons, but a sinner does not leave over an inheritance to his sons, for his wealth and his property are laid away for the righteous, as it is written (Esther 8:2): “And Esther set Mordecai over the house of Haman.”
