Psalms 37:13

The Lord shall laugh at him,.... Have him and his plots in derision, confound his schemes, and disappoint him of his designs, bring him into calamity, and laugh at it; see Psalms 2:4;

for he seeth that his day is coming; either the day of the Lord, which he has appointed to judge the world in, and which comes suddenly, at unawares, as a thief in the night, and is known unto the Lord, though to none else; or the day of the wicked man's ruin and destruction, to which he is appointed, and which is the same; and so the Targum is, "the day of his calamity": which the Lord observes is hastening on, when he will be for ever miserable.
