Charles Spurgeon Commentary Ecclesiastes 12:9

"And further, because the Preacher was wise, he still taught the people knowledge; yea, he pondered, and sought out, [and] set in order many proverbs." — Ecclesiastes 12:9 (ASV)

And moreover, because the preacher was wise, he still taught the people knowledge; yea, he gave good heed, and sought out, and set in order many proverbs.

That man is not fit to teach who does not give good heed, and set his words in order. He who says whatever comes first into his mind only gives out chaff which the wind drives away. But he who would scatter his seed broadcast must take care that he has in his seed-basket good seed that is worth sowing in the broad furrows of the world-field.
