Ecclesiastes 9:13-15

Young's Literal Translation

¹³ This also I have seen: wisdom under the sun, and it is great to me.

¹⁴ A little city, and few men in it, and a great king hath come unto it, and hath surrounded it, and hath built against it great bulwarks;

¹⁵ and there hath been found in it a poor wise man, and he hath delivered the city by his wisdom, and men have not remembered that poor man!
