8. But while man thankfully enjoys life, "let him remember" it will
not last for ever. The "many days of darkness," that is, the unseen
world
(Job 10:21, 22;
Ps 88:12),
also days of "evil" in this world
(Ec 11:2),
are coming; therefore sow the good seed while life and good days last,
which are not too long for accomplishing life's duties.
All that cometh--that is, All that followeth in the evil and
dark days is vain, as far as work for God is concerned
(Ec 9:10).
