Proverbs 12:11

Note, 1. It is men's wisdom to mind their business and follow an honest calling, for that is the way, by the blessing of God, to get a livelihood: He that tills his land, of which he is either the owner or the occupant, that keeps to his word and is willing to take pains, if he do not raise an estate by it (what need is there of that?), yet he shall be satisfied with bread, shall have food convenient for himself and his family, enough to bear his charges comfortably through the world. Even the sentence of wrath has this mercy in it, Thou shalt eat bread, though it be in the sweat of thy face. Cain was denied this, Gen 4:12. Be busy, and that is the true way to be easy. Keep thy shop and thy shop will keep thee. Thou shalt eat the labour of thy hands. 2. It is men's folly to neglect their business. Those are void of understanding that do so, for then they fall in with idle companions and follow them in their evil courses, and so come to want bread, at least bread of their own, and make themselves burdensome to others, eating the bread out of other people's mouths.
