A way - The way of the fool, the way of self-indulgence and self-will.

There is a way which seemeth right unto a man - This may be his easily besetting sin, the sin of his constitution, the sin of his trade. Or it may be his own false views of religion: he may have an imperfect repentance, a false faith, a very false creed; and he may persuade himself that he is in the direct way to heaven. Many of the papists, when they were burning the saints of God in the flames at Smithfield, thought they were doing God service! And in the late Irish massacre, the more of the Protestants they piked to death, shot, or burnt, the more they believed they deserved of God's favor and their Church's gratitude. But cruelty and murder are the short road, the near way, to eternal perdition.

There is a way which seemeth right unto a man,.... As the way of sin and wickedness does, it promising much carnal pleasure and mirth; there is a great deal of company in it, it is a broad road, and is pleasant, and seems right, but it leads to destruction; so the way of the hypocrite and Pharisee that trusts to his own righteousness, and despises others, and even the righteousness of Christ; or however does not submit to it, but tramples upon him, and counts the blood of the covenant an unholy thing, and so is deserving of sorer punishment than the profane sinner; yet on account of his good works, as he calls them, fancies himself to be in a fair way for heaven and happiness; so Popery, through the pomp and grandeur and gaudiness of worship, through the lying miracles of the priests, and the air of devotion that appears in them, seems to be a right way;
but the end thereof are the ways of death; which lead unto eternal death; for that is the wages of sin, let it appear in what shape it will.

The ways of carelessness, of worldliness, and of sensuality, seem right to those that walk in them; but self-deceivers prove self-destroyers. See the vanity of carnal mirth.

end thereof--or, "reward," what results (compare Proverbs 5:4).
ways of death--leading to it.

12 There is a way that seemeth right to one,
But the end thereof are the ways of death.
This is literally repeated in Proverbs 16:25. The rightness is present only as a phantom, for it arises wholly from a terrible self-deception; the man judges falsely and goes astray when, without regard to God and His word, he follows only his own opinions. It is the way of estrangement from God, of fleshly security; the way of vice, in which the blinded thinks to spend his life, to set himself to fulfil his purposes; but the end thereof (אחריתהּ with neut. fem.: the end of this intention, that in which it issues) are the ways of death. He who thus deceives himself regarding his course of life, sees himself at last arrived at a point from which every way which now further remains to him leads only down to death. The self-delusion of one ends in death by the sentence of the judge, that of another in self-murder; of one in loathsome disease, of another in a slow decay under the agony of conscience, or in sorrow over a henceforth dishonoured and distracted life.

Right - There are some evil courses which men may think to be lawful and good. The end - The event shews that they were sinful and destructive.
