Musar su Isaia 40:4

This does not preclude a change in the future. Jacob was אוחז בעקב "holding on to the "heel" (Genesis 25,26) i.e. to humility already from the moment he was born. This is also the mystical dimension of ויבא יעקב שלם, that "Jacob attained perfection" (Genesis 33,18). When Jacob was called ישראל because he prevailed in a struggle with the Divine, this is an allusion to the World to Come, a domain even closer to G–d than the domain of the angels. This is alluded to in Numbers 23,23 by Bileam who said: כעת יאמר ליעקב ולישראל מה פעל א-ל. "Jacob is told at once, Yea, Israel, what G–d has planned." [The author tries to demonstrate that when manipulating the spelling of the name יעקב the name ישרון which is the name used to describe the Jewish people on their highest spiritual level, can be obtained. When one omits the first letter of a "word" representing the "full" spelling of a letter such as the letter י being spelled יוד, this is called a concealed way of spelling the word, נעלם. In our example, if you spell the word יעקב "full" i.e י"וד-ע"ין-ק"וף ב"ית, and you then omit the letters I have highlighted i.e. י-ע-ק-ב, you will be left with ו"ד-י"ן-ו",-י"ת. The numerical value of the last 8 letters is 566, the same as the numerical value of ישרון. Ed.]. This is the mystical aspect of Isaiah 40,4: והיה העקוב למישור, "and the crooked will become straight," an allusion to the perception of Jacob as devious and engaging in deception as claimed by Esau. The "concealed" spelling of these names is a hint of the great good in store for the Jewish people. The three names יעקב-ישראל-ישרון correspond to the שלמות of Jacob in three areas: his body, גוף, his relationship with the material goods of this world, ממון, and his spiritual life, נפש (cf. Rashi on Genesis 33,18). These three areas are the subject of the manner in which we are to relate to G–d with love, i.e. "בכל לבבך, ובכל נפשך, ובכל מאדך. The body will be as much part of an everlasting life in the future we speak of as is the soul in our times. All the Kabbalists are agreed that this is so because the body has been created בצלם אלוקים, in the image of G–d. The names ישראל and ישרון allude to this dual "perfection" of body and soul, i.e. that both will gain everlasting life. The name ישרון symbolizes ישר, that G–d has created man ישר, upright, honest. He could not have done otherwise for ישרים דרכי ה', "the ways of the Lord are upright" (Hosea 14,10). It is relatively easy for a soul, רוח, to return to the Celestial Regions it has come from. When we speak about שלימות ממונו, the Torah means אלוהי כסף ואלוהי זהב לא תעשו (Exodus 20,23), that one must not elevate the value one places on silver and gold as something akin to a deity.
