Comentario sobre Exodo 18:7

ויצא משה AND MOSES WENT OUT — Great honour, indeed, did Jethro receive at that moment, for as soon as Moses went out to Jethro, Aaron, Nadab and Abihu went out, and who was it that saw these go out and would not himself go out? (Midrash Tanchuma, Vayigash 7)

ויצא משה, Moses did not stand on ceremony, using his position to await the arrival of his father-in-law at home, but he went some distance to meet the man in whose house he had received so many favours. We find that Queen Esther, similarly, did not use her elevation to Royalty as an excuse to no longer defer to Mordechai who had raised her. (Esther 2,20 “Esther continued to carry out Mordechai’s instructions as she had done when she lived under his roof.”) Joseph also did not use his exalted position to look down on his brothers. The Chief of the butlers, who had reason to be grateful to Joseph, is an example of ingratitude, as we know from Genesis 40,23, “he did not remember Joseph, in fact he erased him from his memory.”

ויצא משה לקראת חתנו, Moses went out to meet his father-in-law, etc. Seeing that Yitro had pleaded that Moses welcome either his wife or his sons or both, the Torah is at pains to tell us that Moses considered Yitro as deserving to be welcomed by him in his own right, hence the emphasis on לקראת חתנו. Perhaps Moses even went so far as to demonstrate this point by going only to Yitro's tent at this point, ignoring his wife and children till somewhat later. Mechilta makes the additional point that seeing that Moses prostrated himself in front of Yitro this is proof that he went out in order to honour Yitro. Our sages say that Moses honoured Yitro greatly. If the Torah had not stressed that Moses went to meet his father-in-law, how would I have known that he did not go out in order to welcome his wife and sons specifically?
