1:16 I thought to myself,
“I have become much wiser than any of my predecessors who ruled over Jerusalem;
I have acquired much wisdom and knowledge.”
7:23 I have examined all this by wisdom;
I said, “I am determined to comprehend this” – but it was beyond my grasp.
8:9 While applying my mind to everything that happens in this world, I have seen all this:
Sometimes one person dominates other people to their harm.
12:12 Be warned, my son, of anything in addition to them.
There is no end to the making of many books,
and much study is exhausting to the body.
