Question: What’s the difference between putting on Tefillin which the Yeshuos Yaakov holds there is a Torah level mitzvah to wear the entire day but taking the lulav an esrog is only a one moment mitzvah on a Torah level, not the entire day?
Background:
A. The mitzvah by the lulav and esrog is to take them into your hands.
B. The mitzvah of tefillin is to have them on you.
Answer: An action only takes a moment to do so by tefillin it’s only a moment but having them on can be continuous so the mitzvah by tefillin is the entire day.
