Ecclesiastes 1:13; Ecclesiastes 1:12; Ecclesiastes 1:9-11

13 I devoted myself to search for understanding and to explore by wisdom everything being done under heaven. I soon discovered that God has dealt a tragic existence to the human race.
12 I, the Teacher, was king of Israel, and I lived in Jerusalem.
9 History merely repeats itself. It has all been done before. Nothing under the sun is truly new. 10 Sometimes people say, “Here is something new!” But actually it is old; nothing is ever truly new. 11 We don’t remember what happened in the past, and in future generations, no one will remember what we are doing now.
