I am the Teacher. I was king over Israel in Jerusalem.
References for Ecclesiastes 1:12
I applied my mind to investigate and to explore by wisdom all that happens under heaven. It's an unhappy obsession that God has given to human beings.
When I observed all that happens under the sun, I realized that everything is pointless, a chasing after wind.
What's crooked can't be straightened; what isn't there can't be counted.
I said to myself, Look here, I have grown much wiser than any who ruled over Jerusalem before me. My mind has absorbed great wisdom and knowledge.
But when I set my mind to understand wisdom, and also to understand madness and folly, I realized that this too was just wind chasing.
Remember: In much wisdom is much aggravation; the more knowledge, the more pain.
