Psalms 91:8

Only with thine eyes shall thou behold,.... The flying arrow, the walking pestilence, and wasting destruction, and the great devastations made by it:

and see the reward of the wicked; the vengeance of God upon them, and this as a just punishment for their sins; not looking upon it with delight and pleasure, rejoicing in the misery of their fellow creatures, any otherwise than as the glory of divine justice is displayed in it; see Psalms 52:6, the pestilence is always threatened, and it always comes, as a Judgment upon a wicked generation of men; and so it is ever to be considered, and is considered by good men, Leviticus 26:5.
