John Trapp on Proverbs 13:11

Verſ. 11. Wealth gotten by vanity ſhall be diminiſhed] De malè quaſitio [illegible: 1 letter]ix gauget tertius haeres. Horat. Ill gotten goods fly away without taking leave of the owner: leaving nothing but the print of talons to torment him. Prov. 23.5. Many when they have a loſſe in their riches, it is as it were raked out of their bellies, Joh 20.15. A piece of their very heart goes with it.

But he that gathereth by labour, ſhall encreaſe] Howbeit ſometimes it is otherwiſe; Maſter, we have laboured all night and taken nothing. Behold,Luke 4. is it not of the Lord of Hoſts, that the people ſhall labour in the very fire, and the people ſhall weary themſelves for very vanity? Hab. 2.13. There is a curſe upon unlawful practices, though men be induſtrious, as in Jehojakim, Jer. 22.
