Business Proverbs for Financial Planning

Can business proverbs assist with my financial planning? I would like to keep all of my investments on the up and up. It is difficult for me to make decisions with my money because I do not know how well it meshes with my religion. I try to avoid companies that use inhumane methods of production, such as child labor in a foreign country. I also try to avoid those businesses that do harm to the environment, or sale products that I do not believe are good for society as a whole. I would like some additional guidelines to consider when investing my money, so I think that proverbs that are found in the Bible may help me with that. I want to gain as much as possible from my investments, so that I can share my wealth, but I do not want to do so at the cost of my own sanctity.
