ליטעראַטור פֿון בית שני אויף בראשית 4:12

[21] For he says, “Cain was one working the ground” (Gen. 4:2), and, a little later, when he is discovered to have incurred the pollution of fratricide, it is said: “Cursed art thou from the ground, which hath opened her mouth to receive thy brother’s blood from thy hand, with which thou shalt work the ground, and it shall not yield its strength to give it thee” (Gen. 4:12 f.).

[104] For this reason he shall “work” the earth (Gen. 4:12), not “till” it: for every tiller of the soil is a skilled workman, since tilling, too, is a matter of skill, but plenty of untrained men are workers on the soil, plying the task of unskilled labourers to procure the necessaries of life. These people do much mischief in their agricultural operations from not having found anyone to direct them; and if they do anything well, they succeed by accident, not with the aid of reason; but the scientific labours of the tillers of the soil are all of necessity beneficial.
