Hazaz / A Person of Israel, 169; and likewise: "From the gray fortress stone he built himself a house / by the stream he set up a mill, sent the produce of fields / and his power out upon the sea in merchant ships. / But there are times when he leaves his tool of labor / and suddenly becomes another man's" - Nathan Yonatan / Where Are They Still)
