Set the world, or some versions read, eternity. The word is probably “olam” (don’t have a reference handy).
That’s a challenging verse. Seems to me it might refer to the Garden folly. The knowledge of good and evil never could fit in a human heart. It’s a God-sized thang. But men pretend anyhow.
The lie was a promise that not only could a human know good and evil, but he could decide it.
And that’s the basis of modern liberalism.
