James 3:3-5

When we put bits into the mouths of horses to make them obey us, we can guide the whole animal.

Consider ships as well. Although they are so large and are driven by strong winds, they are steered by a very small rudder wherever the pilot is inclined.

In the same way, the tongue is a small part of the body, but it boasts of great things. Consider how small a spark sets a great forest ablaze.
