On Mating with the Preliminary Studies
[176] “Thou shalt live on thy sword and shalt be a slave to thy brother” (Gen. 27:40). He judges it most profitable for him who chooses war instead of peace, who by reason of his inward tumult and rebellion is armed as it were with the weapons of war, that he should become a subject and a slave and obey all the orders that the lover of self-control may impose.
Allegorical Interpretation of Genesis
[193] And if thou shalt consent to become a slave of the wise one, thou shalt cast from thee ignorance and boorishness, plagues of the soul, and be partaker of admonition and correction. For in his prayer thy father says to thee, “To thy brother shalt thou be a slave” (Gen. 27:40); but not now shall this be, for he will not put up with thy restiveness, but when thou shalt have loosed the yoke from thy neck” (ibid.), casting from thee vaunting and insolence which thou didst acquire by yoking thyself to a chariot of passions, of which folly was the driver.
