Ecclesiastes 10:10-12

New Living Translation

¹⁰ Using a dull ax requires great strength,
    so sharpen the blade.
That’s the value of wisdom;
    it helps you succeed.

¹¹ If a snake bites before you charm it,
    what’s the use of being a snake charmer?

¹² Wise words bring approval,
    but fools are destroyed by their own words.
