John Calvin 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. Here follows a contrast similar to that which we encountered in Psalm 2:5, which makes the grace of God toward the faithful even more striking.

His meaning is that even though the wicked may abandon all regard for piety and banish from their minds any thought that human affairs are under God's superintending providence, they will still be made to feel, whether they want to or not, that the righteous, in compliance with God’s command, do not devote themselves in vain to cultivating charity and mercy.

Let them harden themselves as they choose, yet he declares that the honor that God bestows upon His children will be displayed to them, the sight of which will make them gnash their teeth and will stir up an envy that will slowly consume them.

In conclusion, he adds that the wicked shall be disappointed of their desires. They are never content, but are continually thirsting for something, and their confidence is as presumptuous as their avarice is unbounded. Therefore, in their foolish expectations, they do not hesitate to grasp at the whole world. But the prophet tells them that God will snatch from them what they imagined was already in their possession, so that they will always depart destitute and famishing.
