Ecclesiastes - Vanity into Victory (Conclusion)
Ultimately all wisdom comes from God. “Goads” (v. 11) are prodding sticks, and people who master this wisdom literature are similar to “driven nails” in that they are stable and secure. The “one Shepherd” in view could be Solomon, Moses, or, most likely, God (cf. Prov. 2:6).
“Beyond this” (v. 12) evidently refers to beyond the wisdom literature that God has revealed, in view of verse 11. Solomon warned his disciple that looking elsewhere in other books for divine wisdom would only wear him out.
This verse does not say that all study is tiring, though that is true. It means that study of books—other than what God has revealed—in order to learn true wisdom, is an endless, wearisome occupation. This is not to say we should avoid reading books other than the Bible, or that other books do not impart wisdom. It is saying that the main place to look when you want to find true wisdom is God’s Word.
