John Trapp on Psalms 37:13

Verſ. 13, The Lord will laugh at him] See Pſal. 2.4. the righteous alſo ſhall have a time to laugh at him. Pſal. 52.6. and mean while comforteth himſelf with this, that God laugheth at him, and that therefore himſelf hath no great cauſe to cry, ſith riden do irritos reddit, by laughing at them, he blaſteth all their deſigns, and that with diſgrace: men love not to be laughed at.

For he ſeeth that his day is coming] His diſmal day, his Deaths day (which wil alſo be his Doomſ-day) that day wherein God hath determined to ſlay them with their own ſword, and to ſave the Righteous; as it is in the two next verſes. But eſpecially that laſt and great day of the World, wherein Dicetur reprobis Ite, Venite probis.
