Charles Ellicott Commentary Ecclesiastes 9:3

"This is an evil in all that is done under the sun, that there is one event unto all: yea also, the heart of the sons of men is full of evil, and madness is in their heart while they live, and after that [they go] to the dead." — Ecclesiastes 9:3 (ASV)

We have again the sentiments expressed in Ecclesiastes 2:14-16; Ecclesiastes 3:19; Ecclesiastes 5:15; Ecclesiastes 6:12.
