What does Proverbs 22:29 mean?

Solomon commends "skillful" work in this final verse of Proverbs chapter 22. The word "skillful" here is from the Hebrew word mahiyr, which can also mean "timely" or "prompt." The general idea is that of a worker who is diligent and capable of finishing excellent work in good time. Such a person is more likely to attract the favor of powerful people. While worldly success is not guaranteed, it's certainly true that diligent and efficient people have a better likelihood of success than those who are irresponsible.

The benefit of working diligently applies today. An employer or supervisor notices the person who works with purpose to complete tasks in a timely manner. A good employer rewards such employees by promoting them, or by giving them a raise, or by doing both. Many companies conduct employee evaluations in which a supervisor grades each employee on several factors. The evaluation might also include a reference to how quickly the employee performs each task. A yes or no is given for "performs each task in a timely manner." A lazy employee has good reason to dread his evaluation, but a diligent employee has nothing to fear.
