Psalms 34:21

Evil shall slay the wicked -That is, his own wicked conduct will be the cause of his destruction. His ruin is not arbitrary, or the mere result of a divine appointment; it is caused by sin, and is the regular and natural consequence of guilt. In the destruction of the sinner, there will not be any one thing which cannot be explained by the supposition that it is the regular effect of sin, or what sin is, in its own nature, suited to produce. The one will measure the other; guilt will be the measure of all that there is in the punishment. And they that hate the righteous -Another term for the wicked, or a term designating the character of the wicked in one aspect or view.
