Hillel said in Pirkei Avot 4:5:
Anyone who derives worldly benefit from the words of the Torah removes his life from the world.
The Rambam in his commentary thereon explores the idea of financially benefiting from Torah and strongly rejected the notion that Jews must financially help other Jews study Torah:
When we look into the words of the rabbis... we do not find among them that they were requesting money from people and they did not collect money for the honored and precious academies... Rather, we find, in each and every generation, [that poor scholars lived from] the work in which they engaged.
He considered that depending on the charity of others to study Torah is a form of benefitting from Torah and therefore forbidden.
Is it true that nothing in the Torah or words of the Sages says to support Torah scholars to free them from worldly concerns?
