Albert Barnes Commentary Psalms 112:10

"The wicked shall see it, and be grieved; He shall gnash with his teeth, and melt away: The desire of the wicked shall perish." — Psalms 112:10 (ASV)

The wicked shall see it, and be grieved - They will see his prosperity; they will see the evidence that God approves his character and his conduct. The word translated “grieved” means rather to be angry or enraged. Perhaps the word “fret” would best express the sense.

He shall gnash with his teeth - As indicative of hatred and wrath. See the notes at Psalm 37:12.

And melt away - Disappear - as snow melts; or as a snail (see the notes at Psalm 58:8); or as waters that run away (see the notes at Psalm 58:7); or as wax (see the notes at Psalm 68:2). Their wrath will be of no avail, for they themselves will soon disappear.

The desire of the wicked shall perish - He will not be able to accomplish his desire or to carry out his purposes. He will be disappointed, and all his cherished plans will come to nothing.

This is in strong contrast with what the psalm says would occur to the righteous. They would be prospered and happy; they would be able to carry out their plans; they would be respected while living, and remembered when dead.

They would find God intervening on their behalf in the darkest hours; they would be firm and calm in the day of danger and of trouble; they would put their trust in the Lord, and all would be well. Surely there is an advantage in our world in being a friend of God.
