ציטירנדיקער פּירוש אויף ישעיהו 11:10

Solomon informed us in this verse that a righteous person and a wicked person are absolute opposites of one another. Whereas words spoken by the righteous reflect his wisdom, the words spoken by the wicked person reflect the opposite. This is what is meant by Psalms 1,3: “he is like the tree planted beside streams of water, which yields its fruit in season and whose foliage never fades;” the tree produces leaf and fruit. This is a natural phenomenon, a law of nature which became part of trees alluded to already on the third day of creation when G’d gave the directive to earth: תדשא הארץ, “the earth is to produce vegetation, etc.” The leaf itself performs a useful function in that it protects the fruit against heat by the shade it provides. Nonetheless, the fruit is what counts. Similarly, the righteous is the person, the fruit who counts, he too has “leaves,” similar to the leaves on the tree. His everyday conversation dealing with mundane matters are described as his leaves, whereas his words of Torah are described as his fruit. Just as the leaves on a tree perform an important function, so does even the mundane conversation of the righteous.
When our sages in Avodah Zarah 19 interpreted the words “and his leaves do not wither,” (Psalms 1,2) they said that it means that the casual conversations of the righteous are of similar value to the value of the leaves for the fruit of the tree, [for all the above reasons Solomon mentioned here that the mouth of the wise yields up wisdom]. The word ינוב is used in connection with agricultural produce such as in Isaiah 27,6 ומלאו פני תבל תנובה, “and the face of the world will be covered with fruit.” We also find that word in Lamentations 4,9 as referring to the produce of the field. This is also the subject under discussion in Isaiah 57,19 בורא ניב שפתים, “the One Who creates the fruit of the lips.” Speech may be perceived as the “fruit of the lips.” The righteous trains himself so carefully to utter only words of wisdom that wisdom becomes integral to his personality, he personifies it. It is similar to the fruit which represents the essence of the tree.
The words: “the tongue of the perverted shall be cut off,” describe the wicked person who is the opposite of the righteous, something which is discernible first and foremost in the way he uses his tongue. Seeing that this wicked person indulges in so much slander, libel, etc., Solomon curses him saying that his tongue ought to be cut off. It is the way of the Torah to attach blessings to the righteous and curses to the wicked. This is why we have the famous saying זכר צדיק לברכה ושם רשעים רקב, “the memory of the righteous is a source of blessing, whereas the name of the wicked will rot.” (Proverbs 10,7) It is well known that the virtue of humility is associated with wisdom, whereas arrogance is a characteristic of the wicked. Just as wisdom is “the fruit” of the righteous, so arrogance is “the fruit“ of the wicked. This is why Solomon says (Proverbs 14,3) “in the mouth of the fools is a rod (branch) of pride, but the lips of the wise protect them.” The source of arrogance is in the heart of the fool and its branch becomes manifest in his mouth. The prophet Isaiah 11,10 illustrated this when he spoke of חוטר describing it as a “branch,” i.e. “a branch comes forth from the trunk of Yishai.” Branches cannot grow unless there is a trunk to support them. There is no point in describing the emergence of such a branch unless it is going to bear fruit. The fruit of such branches of the foolish, the wicked, are words of arrogance, scorn. David paraphrases the same sentiment in Psalms 123,4 הלעג השאננים, הבוז לגאיונים, “the scorn of the complacent, the contempt of the haughty.” In other words, the fool gets so used to being arrogant that arrogance becomes second nature to him. Seeing that he “branch” of arrogance is so often in his mouth, it is a foregone conclusion that it will bear fruit, i.e. that he cannot restrain himself from saying things which reveal his arrogance to all his listeners. On the other hand, the wise are protected by their very lips against their mouths saying things they should not say.
Basically, the logic in all this is that the righteous is drawn to preoccupy himself with matters of the soul, matters which are of eternal value and meaning; the wicked, on the contrary, is preoccupied with transient values, matters which sooner or later cease to exist and have meaning. It is a well known fact that the very definition of the word “body” means that it is something “earthy,” will revert to dust, whereas the soul is something which came from heaven. As long as man is alive in this terrestrial life, he is drawn equally toward earth and heaven. He is drawn towards heaven due to his soul, and towards earthy matters due to his body. Therefore, when Moses cautioned the people to keep the Torah and its commandments, he used as witnesses heaven and earth, both of which are conceptually close to man. This is why he said:

תדרשו, you shall seek out this place to worship and to offer your sacrifices, as per Isaiah 11,10 אליו גויים ידרשו, “nations will seek Him out there.”

מטרף בני עלית. These words are understood by the Midrash as referring to four people whom Yehudah saved personally, i.e. Joseph, Tamar, Peretz and Zerach. G’d saved four more people, all of them descendants of Yehudah, i.e. Daniel, Chananyah, Mishael and Azaryah. Thus far Bereshit Rabbah. The Midrash tells us that G’d saved Daniel from the pit of lions as a reward for Yehudah having saved Joseph from the pit. He saved the three righteous men Chanayah, Mishael and Azaryah from a fiery death at the hands of Nebuchadnezzar’s furnace (Daniel 3,25) because Yehudah their ancestor had saved Tamar and the twins Peretz and Zerach inside her womb from death by burning.
The Midrash refers to further repercussions in the distant future due to Yehudah’s conduct, citing the fact that the first Temple was built by Solomon a descendant of Yehudah whereas the second Temple was built by Zerubabel, also a descendant of Yehudah. (compare Chagai 2,23), Zecharyah 4,9 and Zecharyah 4,7) The third Temple which we hope will be built soon will be erected by the King Messiah, also of David’s i.e. Yehudah’s descent. We base this on Isaiah 11,10.

ולו יקהת עמים means AND UNTO HIM [SHALL BE] AN ASSEMBLAGE OF PEOPLES. יקהת is a noun from the root יקה and is not a verbal form although it has the appearance of one, for the י is one of the root-letters as it is in the word יפעתך (Ezekiel 21:20) “thy brightness” from root יפע, only that it is sometimes omitted. There are many root-letters that are subject to this rule and are known as עיקר נופל (root-letters that may be omitted) as, for example, the נ of נוגף and of נושך and the א of אחותי in (Job 13:17) ואחותי באזניכם (where the root is חוה) “and let my declaration be in your ears”, and the אבחת of א in the phrase (Ezekiel 21:20) אבחת חרב “the point of the sword”, or the א in אסוך in the phrase (2 Kings 4:2) (אסוך שמן) (root סוך) “a pot of oil”. So, too, here, ויקהת a noun (from a root יָקַה to assemble, as שמחה the construct of which is שמחת from שמח) — an assembly of nations. And so it is actually said with reference to the Messiah, (Isaiah 11:10) “Unto him shall the nations seek”. Of similar meaning is the word יקהת in (Proverbs 30:17) “the eye that mocketh at his father, and despiseth ליקהת אם i.e. despiseth “the gathering of wrinkles in the mother’s face” (due to old age). In the Talmud we find a similar meaning of the root .יקה: “they sat and gathered assemblies (ומקהו אקהתא) in the streets of Nehardea” (Tr. Yevamot 110b). It could have also said קהיית instead of יקהת.
