Yet because the wicked do not fear God, it will not go well with them, and their days will not lengthen like a shadow.
Solomon, in the beginning of the chapter, had warned us against having any thing to do with seditious subjects; here, in these verses, he encourages us, in reference to the mischief of tyrannical and oppressive rulers, such as he had complained of before, Ecc 3:16; Ecc 4:1. 1. He had observed many such rulers, Ecc 8:9.
Commenting on Ecclesiastes 8:9-13
But it shall not be well with the wicked,.... It shall be ill with him; more is designed than is expressed, Isa 3:11; in life they have no solid peace and comfort; at death they will be turned into at judgment they will hear the awful sentence, "Go, ye cursed", and will be in torment to all eternity, Mat 25:41; neither shall he prolong his...
neither shall he prolong--not a contradiction to Ecc 8:12. The "prolonging" of his days there is only seeming, not real. Taking into account his eternal existence, his present days, however seemingly long, are really short. God's delay (Ecc 8:11) exists only in man's short-sighted view.
