How much may one charge for helping to reload a colleague's animal?
Halacha 7 rules that unloading (peri'kah) is a Torah mitzvah performed for free; loading (te'inah) is a mitzvah for which one may charge a fee.
Question 2
A passerby finds two animals: one fallen under its load, one already unloaded needing reloading. Which does he help first?
Halacha 13 rules that when the two owners are both friends or both enemies, one helps the fallen animal first because of tza'ar ba'alei chayyim — animal suffering is the priority.
Question 3
A passerby encounters a fallen animal: one owner is his enemy (a Jew he saw sinning), one is his friend. Whose animal should he help first?
Halacha 13 rules that when choosing between an enemy and a friend, one must help the enemy first in order to subdue the evil inclination (yetzer hara) and overcome personal enmity.
Question 4
What is the maximum distance at which one is obligated to notice and help with a fallen animal?
Halacha 6 specifies that the Sages measured the obligating distance as 266⅔ cubits (one seventh and a half of a mil); beyond that distance, one is not obligated to help.
Question 5
The Rambam closes Chapter 13 (and the entire Hilchot Rotze'ach) affirming that the Torah cares for the lives of the wicked and righteous alike. What is his source?
Halacha 16 cites Ezekiel 33:11 — God's declaration that He desires the wicked to repent and live — as the basis for the Torah's concern for every Jewish soul, regardless of wickedness.
