Solomon
Ecclesiastes 6:6BSB·traditional attribution

even if he lives a thousand years twice over but fails to enjoy his prosperity. Do not all go to the same place?

Matthew Henry Presbyterian @wholebiblehenry

Solomon had shown, in the close of the foregoing chapter, how good it is to make a comfortable use of the gifts of God's providence; now here he shows the evil of the contrary, having and not using, gathering to lay up for I know not what contingent emergencies to come, not to lay out on the most urgent occasions present.

Commenting on Ecclesiastes 6:1-6

John Gill Reformed Baptist @doctorgill

Yea, though he live a thousand years twice told,.... Or two thousand years, which no man ever did, nor even one thousand years; Methuselah, the oldest man, did not live so long as that; this is than twice the age of the oldest man: there is one sort of the Ethiopians, who are said (a) to live almost half space of time longer than usual...

Jamieson-Fausset-Brown Reformed @jfbcommentary

If the miser's length of "life" be thought to raise him above the abortive, Solomon answers that long life, without enjoying real good, is but lengthened misery, and riches cannot exempt him from going whither "all go." He is fit neither for life, nor death, nor eternity.
