Numbers 21:4

דרך ים סוף BY THE WAY OF THE RED SEA — As soon as Aaron died and this war came upon them they turned back on the way to the Red Sea; this was the way on which they had turned back when there had been enacted against them the decree that they must wander in the wilderness in consequence of their murmuring after having received the report of the spies, as it is said, (Deuteronomy 1:40), “And take your journey into the wilderness by the way to the Red Sea”. Here they went back seven stages, as it is said, (Deuteronomy 10:6), “And the children of Israel journeyed from Beeroth-bene-jaakan to Moserah; there Aaron died”. But did he really die at Moserah; was it not at Mount Hor that he died?” But the explanation is, that there (at Moserah) they again mourned and lamented for him just as though he there lay dead before them. Go and examine the list of the stages (Numbers 33:31—37) and you will find that there are seven stages from Moserah to Mount Hor (Midrash Tanchuma, Chukat 18). לסבב את ארץ אדום TO GO ROUND THE LAND OF EDOM — to go round it, because they would not permit them to pass through their land. ותקצר נפש העם בדרך AND THE SOUL OF THE PEOPLE WAS MUCH DISCOURAGED BECAUSE OF THE WAY — because of the difficulties of the journey which were so hard for them. They said: Now we are close enough to enter the land, and yet we have to turn back. Just so had our fathers to turn back and they stayed in the wilderness thirty eight years until this day. —Consequently their soul became discouraged because of the hardship of the journey. In O. F., En cure del tour. — It would not be correct to say that ותקצר נפש העם בדרך means “[and the soul of the people was discouraged] while they were on the journey” and that it (the text) does not explain what it was discouraged through, for in every passage in Scripture where you find the phrase “the soul being discouraged”, it is there explained through what it became discouraged (the preposition ב being prefixed to the word that expresses the cause of discouragement). For example, (Zechariah 11:8) “And my soul became impatient of them (בהם)”, and, for example, (Judges 10:16): “And His soul became impatient with the enemies on account of the misery (בעמל) they inflicted upon Israel”. To anything that is hard for a man to bear the expression “the shortening of soul” (קצור נפש) is applicable - he is like a person upon whom trouble comes and his mind is not large enough to contain that matter and there is no room in his heart for that worry to abide there. Of the thing that causes the trouble the term “large” is used, denoting that it is too huge and heavy for a person. For example, (Zechariah 11:8) וגם נפשם בחלה בי, which signifies “(And also their souls] were great upon Me”; (Job. 10:16), “And it becomes large (it is a burden to Thee) even that Thou huntest me as though I were a lion”. (See Rashi on these verses and on Niddah 47a). To sum up the explanation: the phrase “shortening of the soul through a thing” signifies that one cannot bear it — that the mind cannot bear it.

וַיִּסְע֞וּ מֵהֹ֤ר הָהָר֙ דֶּ֣רֶךְ יַם־ס֔וּף לִסְבֹ֖ב אֶת־אֶ֣רֶץ אֱד֑וֹם וַתִּקְצַ֥ר נֶֽפֶשׁ־הָעָ֖ם בַּדָּֽרֶךְ׃

And they journeyed from mount Hor by the way of the Sea of Suf, to compass the land of Edom: and the soul of the people was much discouraged because of the way.
