'Heaven' in the Bible

I also {explored} {the effects of indulging my flesh} with wine. My mind guiding me with wisdom, {I investigated} folly so that I might discover what [is] good under heaven for {humans} to do {during the days of their lives}.

For everything there [is] an appointed time, a time for every matter under heaven:

For no one knows [whether] the spirit of a human ascends [to heaven] and [whether] the spirit of the beast descends to the ground!

Do not be rash with your mouth, and do not let your heart be quick to utter a word before God. For God is in heaven, and you [are] on earth; therefore, let your words be few.
