in which he teaches that it is the Divine will that we act for the benefit of our enemies and forget our hate when they are suffering
The commandment to "nevertheless raise it with him" is stated in the text concerning an enemy's ass collapsing from the weight of its burden, "When you see the ass of your enemy lying under its burden and would refrain from raising it, you must nevertheless raise it with him", also includes the general Divine will and idea that we act for the benefit of our enemies and forget our hate when they are suffering, that we assist and support them to the best of our ability. The person who instils this attribute deep within their heart and helps their enemy in every way and at every opportunity thereby fulfills the Divine will and desire.
