Charles H. Spurgeon on Psalms 37:11

And shall delight themselves in the abundance of peace. Surely when the glory of the Lord covers the earth, and all the kingdoms of this world become the kingdoms of the Prince of Peace, and the wicked one is rooted out, we may well expect peace in rich abundance. W. Wilson.

Verses 12-13. Note how the gesture of the wicked in gnashing their teeth is returned to them in the Lord's scornful laughter at their devices. Their plotting, too, is countermined by that winding up of all plots, which the Lord knoweth, though they are wilfully ignorant of it. C. H. S.
