Can one be obligated for muzzling one’s animal or crossbreeding animals if he caused it to happen by speaking to the animal and not by doing any action? Details regarding a worker eating on the job are further discussed. Does one need to be working with both one’s hands and legs (like the ox who can’t be muzzled)? If one is working with one type, can one eat a different type in the field? Can one eat from the same type in a different area? Can one eat while one is walking from one place to another?
