'Heaven' in the Bible

And I applied my heart to seek and to search out by wisdom concerning all that is done under heaven: it is a sore travail that God hath given to the sons of men to be exercised therewith.

I searched in my heart how to cheer my flesh with wine, my heart yet guiding me with wisdom, and how to lay hold on folly, till I might see what it was good for the sons of men that they should do under heaven all the days of their life.

For everything there is a season, and a time for every purpose under heaven:

Be not rash with thy mouth, and let not thy heart be hasty to utter anything before God; for God is in heaven, and thou upon earth: therefore let thy words be few.
