The first requirement is to have no thought or desire or "mind to injure one another" (4:13). Wrong doing begins with wrongful thinking.
Next we must "live peaceably" (4:13). We must seek peace. Peace does not just happen. It must be created, desired, worked for, and maintained.
And third, Benjamin taught that if people have done good things to us, we must reciprocate and "render to every man according to that which is his due" (4:13). This may involve paying compensation, or extending human dignity, or giving verbal praise and recognition for what they have done. "Rendering" is a very powerful concept. It means to "rend," to "tear open" and give generously and willingly. One of my granddaughters has been babysitting for a young mother in our stake who has been very grateful for what my granddaughter has done, and she has abundantly and sincerely praised her for her being able and willing to take care of these little children. My granddaughter goes over there voluntarily. She loves going over and helping because she is getting this positive praise. It has had a powerful effect on her whole personality, even giving her confidence in what she is doing in school and a lot of other things. She gets paid a little bit for the babysitting, but she does not go for the money. She goes for the praise and kind recognition for the service she has given.
Toward the end of this section of his speech, Benjamin returns to this theme. In Mosiah 4:28, it is interesting that he specified that an individual had to return the thing that he or she had borrowed. In ancient Mesopotamian laws dealing with loans, if someone borrowed a cow or an ox to do their plowing, or borrowed a donkey, a borrower could not just give another donkey. They had to return the very animal that they borrowed, and that helped to preempt arguments about equivalent value and things like that. Thus, if they borrowed something, they needed to give back the actual thing. Benjamin’s people, likewise, were probably not very far advanced financially. No ancient society had what we would call banks or mortgage companies. They had weights and measures for handling sales at the market place, but most didn’t have currency. Thus, it is interesting that Benjamin wanted people to be precise in their paying back of anything that they owed someone else.
But the point here is not just that we give it back. Benjamin wants to be sure that there are no arguments, no disputations, but that by giving back "according as he doth agree," that person avoids committing sin himself and also prevents an argument that might lead your "neighbor to commit sin also" (4:28).
