The purpose is that you may walk in the way of good people and that the paths of the righteous ones you may keep. For the upright are the ones that will reside in the earth, and the blameless are the ones that will be left over in it. As regards the wicked, they will be cut off from the very earth; and as for the treacherous, they will be torn away from it. Proverbs 2:20-22

Thus you will walk in the ways of good men and keep to the paths of the righteous. For the upright will live in the land, and the blameless will remain in it; but the wicked will be cut off from the land, and the unfaithful will be torn from it. Proverbs 2:20-22
The righteous themselves will possess the earth, And they will reside forever upon it. Psalm 37:29

The righteous will inherit the land and dwell in it forever. Psalm 37:29
There are many other scriptures that use the word “land” or "earth" in identifying man's indefinite domain. The writing of Proverbs was completed in 717 B.C.E. This was long before the fundamental scientific understanding of the earth as a spherical planetary body in a solar system of nine planets. Some translations aside from the New World Translation use the word “earth” instead of “land.”

There's only one organization that teaches humanity will reside indefinitely in their natural habitat (the earth). How should Proverbs 2:20-22 and other scriptures that specify the earth (or land) as man's eternal home instead of a supernatural dimension like "heaven" be understood?
