ליטעראַטור פֿון בית שני אויף בראשית 28:7

[70] Thus we read in the case of Jacob, when he was sent to marry into his mother’s family, “Jacob heard his father and mother, and went to Mesopotamia” (Gen. 28:7). “Heard them,” it says, not their voice or words, for the practiser must be the imitator of a life, not the hearer of words, since the latter is the characteristic mark of the recipient of teaching, and the former of the strenuous self-exerciser. Thus this text too is meant as a lesson to us that we may realize the difference between a learner and a practiser, how the course of one is determined by what a person says, the other by the person himself.
