[70] For it is said, in the case of Jacob when he was sent away to form a marriage among his kinsmen, "Jacob listened to his mother and his father, and went into Mesopotamia." [21] He listened not to their voice, nor to their words, for it was fitting that he who was an imitator of their actions should be a practiser of virtue not a listener to speeches. For this is the peculiar character of one who is being taught, but the other is the mark of one who is enduring labours, in order that from this instance we may comprehend the difference between a practiser and a learner, the one being regulated with regard to him who is speaking, and the other with regard to his speech.
