For he will not often consider the [troubled] days of his life, because God keeps him occupied and focused on the joy of his heart [and the tranquility of God indwells him].

For who [limited by human wisdom] knows what is good for man during his lifetime, during the few days of his futile life? He spends them like a shadow [staying busy, but achieving nothing of lasting value]. For who can tell a man what will happen after him [to his work, his treasure, his plans] under the sun [after his life is over]?

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.
