'Inheritance' in the Bible

For sometimes people who strive to obtain wisdom, knowledge, and equity leave everything as an inheritance to a person who never worked for it. This, too, is pointless and greatly troublesome.

I concluded that it is worthwhile for people to find joy in their accomplishments, because that is their inheritance, since who can see what will exist after them?

Wisdom is good with an inheritance: and by it there is profit to them that see the sun.
