Albert Barnes Commentary Ecclesiastes 8:8

"There is no man that hath power over the spirit to retain the spirit; neither hath he power over the day of death; and there is no discharge in war: neither shall wickedness deliver him that is given to it." — Ecclesiastes 8:8 (ASV)

Neither has he power - Rather: “and there is no power.” Compare Ecclesiastes 3:19.

No discharge ... - That is, “No exemption from the final hour of struggle between life and death.”

Wickedness - Though the life of the wicked may be prolonged (Ecclesiastes 7:15), yet wickedness itself has no inherent power to prolong that life.
