We find that after the Torah describes how Hashem made a covenant with the Jewish people he immediately made them promise they would support Torah learning, as it says, ‘Cursed is he who does not support this Torah’, and all the curses were repeated as blessings. Our Sages explained that even if someone is so busy he cannot learn at all, if e supports Torah he is blessed. On the other hand if he did learn and taught and kept the Torah but did not support it even though he could have, is considered cursed. Thus, with this commandment Hashem included all Jews in the tremendous merit of supporting Torah learners, since without it He knew there would be no Judaism.

"והאמת בלתי שום ספק כלל, שאם היה העולם כולו מקצה עד קצהו פנוי חס ושלום אף רגע אחד ממש מהעסק והתבוננות שלנו בתורה, כרגע היו נחרבים כל העולמות, עליונים ותחתונים, והיו לאפס ותוהו חס ושלום". (נפש החיים) 1
