((Learning and the Fifth Commandment))
240, 13. In case of a conflict of duties, studying the Torah takes precedence over the duty of honoring parents.

Their Torah protects them.
Similarly, scholars are free from having to pay any kind of tax or impost, whether it be a tax placed on the citizens as a whole, or on
