Solomon, in the Scriptures, expresses the same kind of frustration with life we find today. He became convinced that life is meaningless.
He looked to the same sources for meaning that are common in modern society: wealth, wine, women, song, knowledge, and entertainment. (See the Bible book of Ecclesiastes).
In describing his despair, Solomon used a recurring phrase.
On 29 occasions, we find the phrase, “under the sun.” He says everything under the sun is meaningless; “there is no profit in anything done under the sun.”
