{c} Delight is not proper for a fool; much less for a servant to have rule over princes.

(c) The free use of things are not to be permitted to him who cannot use them correctly.

Wesley's Notes

19:10 Delight - To live in pleasure and outward glory, doth not become him, nor suit with him; because prosperity corrupts even wise men, and makes fools mad; and because it gives him more opportunity to discover his folly, and to do mischief both to himself and others.

Jamieson-Fausset-Brown Bible Commentary

10. (Compare Pr 17:7). The fool is incapable of properly using pleasure as knowledge, yet for him to have it is less incongruous than the undue elevation of servants. Let each abide in his calling (1Co 7:20).

Matthew Henry's Concise Commentary

19:3. Men run into troubles by their own folly, and then fret at the appointments of God. 4. Here we may see how strong is men's love of money. 5. Those that tell lies in discourse, are in a fair way to be guilty of bearing false-witness. 6. We are without excuse if we do not love God with all our hearts. His gifts to us are past number, and all the gifts of men to us are fruits of his bounty. 7. Christ was left by all his disciples; but the Father was with him. It encourages our faith that he had so large an experience of the sorrows of poverty. 8. Those only love their souls aright that get true wisdom. 9. Lying is a damning, destroying sin. 10. A man that has not wisdom and grace, has no right or title to true joy. It is very unseemly for one who is a servant to sin, to oppress God's free-men.
