Don't spread false rumors. Don't plot with evil people to act as a lying witness.
Don't take sides with important people to do wrong. When you act as a witness, don't stretch the truth to favor important people.
But don't privilege unimportant people in their lawsuits either.
When you happen to come upon your enemy's ox or donkey that has wandered off, you should bring it back to them.
When you see a donkey that belongs to someone who hates you and it's lying down under its load and you are inclined not to help set it free, you must help set it free.
Don't undermine the justice that your poor deserve in their lawsuits.
