Psalms 37:11

But the meek shall inherit the earth
(See Gill on Psalms 37:9); of this character (See Gill on Psalms 22:26). Our Lord seems to refer to this passage in ( Matthew 5:5 ) ;

and shall delight themselves is the abundance of peace;
of spiritual peace enjoyed in a way of believing, arising from a comfortable view of interest in the blood, righteousness, and sacrifice of Christ; and of all happiness and prosperity in the kingdom of Christ here on earth, at which time there will be abundance of peace, ( Psalms 72:7 ) ; or of eternal peace in the world to come, which will be a state of uninterrupted and unspeakable peace; see ( Psalms 37:37 ) ; all which afford inconceivable delight and pleasure; and therefore such have no need to fret and be envious at the fading happiness of wicked men.
