Ecclesiastes 10:10-12

Christian Standard Bible

¹⁰ If the ax is dull, and one does not sharpen its edge,
then one must exert more strength;
however, the advantage of wisdom is that it brings success.
¹¹ If the snake bites before it is charmed,^(A)
then there is no advantage for the charmer.^[a]
12 The words from the mouth of a wise person are gracious,^(B)
but the lips of a fool consume him.^(C)
