Proverbs 20

It took me about 2 minutes to read through these observations of Solomon. Twice Solomon mentions honest business practices; vss 10 & 23. God condemns the practice of preferential pricing and different scales. Knowing that these affect everybody God wants his people to be ethical in their business practices. Hard work is to be the source of reward in business, not dishonest scheming.  There are other verses in this chapter that address the same truths as well.
