Ecclesiastes 1:13

I gave my heart — Which phrase denotes his serious and fixed purpose, and his great industry in it. To search — To seek diligently and accurately. By wisdom — By the help of that wisdom wherewith God had endowed me. Concerning — Concerning all the works of God and men in this lower world; the works of nature; the works of Divine providence; and the works and depths of human policy. This travel — This difficult and toilsome work of searching out these things, God hath inflicted as a just punishment upon man for his eating of the tree of knowledge. To be exercised — To employ themselves in the painful study of these things.
