25 The righteous eateth to the satisfying of his soul: but the belly of the wicked shall want.
Note, 1. It is the happiness of the righteous that they shall have enough and that they know when they have enough. They desire not to be surfeited, but, being moderate in their desires, they are soon satisfied. Nature is content with a little and grace with less; enough is as good as a feast. Those that feed on the bread of life, that feast on the promises, meet with abundant satisfaction of soul there, eat, and are filled.
2. It is the misery of the wicked that, through the insatiableness of their own desires, they are always needy; not only their souls shall not be satisfied with the world and the flesh, but even their belly shall want; their sensual appetite is always craving. In hell they shall be denied a drop of water.
– Matthew Henry Commentary
