'Everything' in the Bible

There is a season (a time appointed) for everything and a time for every delight and event or purpose under heaven—

He has made everything beautiful and appropriate in its time. He has also planted eternity [a sense of divine purpose] in the human heart [a mysterious longing which nothing under the sun can satisfy, except God]—yet man cannot find out (comprehend, grasp) what God has done (His overall plan) from the beginning to the end.

I have seen everything during my [fleeting] days of futility; there is a righteous man who perishes in [spite of] his righteousness, and there is a wicked man who lives a long life in [spite of] his wickedness.

Also, do not take seriously everything that is said, so that you will not hear your servant cursing you,

But beyond this my son, [about going further than the words given by one Shepherd], be warned: the writing of many books is endless [so do not believe everything you read], and excessive study and devotion to books is wearying to the body.
