'Whom' in the Bible

There was a certain man—without a dependent, having neither a child nor a brother, yet there was no end to all his labor. Indeed, his eyes were not satisfied with riches and he never asked, “For whom do I labor and deprive myself of pleasure?” This too is vanity (a wisp of smoke, self-conceit); yes, it is a painful effort and an unhappy task.

Also, every man to whom God has given riches and possessions, He has also given the power and ability to enjoy them and to receive [this as] his [allotted] portion and to rejoice in his labor—this is the gift of God [to him].

a man to whom God has given riches and wealth and honor, so that he lacks nothing of all that he desires, yet God has not given him the power or capacity to enjoy them [all those things which are gifts from God], but a stranger [in whom he has no interest succeeds him and] enjoys them. This is vanity and it is a [cause of] great distress.

Live joyfully with the wife whom you love all the days of your fleeting life which He has given you under the sun—all the days of vanity and futility. For this is your reward in life and in your work in which you have labored under the sun.
