They shall lie down alike in the dust - The emphasis here is on the word “alike” - יחד yachad. The idea is, that they should die “in a similar manner.” There would be no such difference in the mode of their death as to determine anything about their character or to show that one was the friend of God, and that the other was not. The friends of Job had maintained, that that could be certainly known by the divine dealings with people, either in their life, or in their death. Job combats this opinion, and says, that there is no such marked distinction in their life, nor is there any certain indication of their character in their death. Prosperity often attends the wicked as well as the righteous, and the death of the righteous and the wicked resemble each other.
And the worms shall cover them - Cover them “both.” They shall alike moulder back to dust. There is no distinction in the grave. There is no difference in the manner in which they moulder back to dust. No argument can be drawn respecting their character from the divine dealings toward them when in life - none from the manner of their death - none from the mode in which they moulder back to dust. On the reference to the “worm” here, see the notes at Job 14:11.
