"Help shall you help with him": What is the intent of this? From (Devarim 24:4) "Lift up shall you lift up with him," I would know only of unloading and loading (the load itself). Whence do I derive (the same for lifting) the animal itself? From "lift up shall you lift up with him." — when you are like him (i.e., when he also does his part).
Help Shall You Help with Him, the Torah Commands Assisting Someone
