Psalm 37:11

But the meek shall inherit the earth; and shall delight themselves in the abundance of peace.

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.
