הֵ֭מָּה כָּרְע֣וּ וְנָפָ֑לוּ וַאֲנַ֥חְנוּ קַּ֝֗מְנוּ וַנִּתְעוֹדָֽד׃
זײ בײגן זיך און פֿאַלן, און מיר הײבן זיך און שטעלן זיך װידער. העלף דו, גאָט!

At this point, an accomplished and erudite young warrior presents himself and audaciously (Psalms 20:9) joins the campaign, full of spirit. His tongue speaks mighty things (Psalms 12:4). The great were astonished by him, silenced and unable to reply (Job 32:15); tongue tied (Job 29:10).

Seeing that it is impossible for a human being while part of a body to divest himself totally of bodily needs and concerns, we can appreciate what our sages said that contrary to the name Avraham which replaced the name Avram, the name Yisrael did not replace the name Yaakov. It reflected the fact that this Yaakov had attained an additional dimension in his personality development (compare Berachot 13). The name Yaakov henceforth became subordinate to that of Yisrael. The use of these names teaches amongst other matters that if someone makes his spiritual dimension subordinate to his physical, terrestrial concerns this “kills” him, leads to his death sooner or later. This is what David had in mind when he said in Psalms 22,30: “all those who in full vigor shall eat and prostrate themselves, all those at death’s door whose spirit lag, shall bend the knee before Him.” David refers to people who make a point of first tasting all the pleasures of terrestrial life before prostrating themselves before G’d as having their priorities reversed. As a result, such people experience death in a very real sense of the word. In the verse we just quoted the word יכרעו, “they will bend the knee” does not refer to something similar to השתחוה, “prostrating” oneself (before G’d). Rather, it is similar to Psalms 20,9. In that psalm it is used as meaning falling down and not rising up again. This is the punishment for having had one’s priorities mixed up. When the people mentioned in Psalm 22 finally decide to “give to Caesar what is Caesar’s,” i.e. to also make an obeisance to G’d as an afterthought, it is too late. They had not lifted a finger to secure their share in eternity while there was time.
Upon closer examination you will find that when the Torah employs the name Yaakov to describe our patriarch it refers to his terrestrial concerns, concerns which are indispensable for any human being, whereas when it switches by calling him Yisrael it refers to his spiritual concerns, matters which are largely abstract. This is what the prophet (Isaiah 43,1) had in mind when he said: ”who created you O Yaakov, who formed you O Yisrael?” In connection with the name Yaakov, the prophet only mentioned the word בריאה, a primitive kind of creation, whereas in connection with spiritual parts of man the prophet speaks of a more sophisticated product, one that has undergone יצירה, an advanced stage of formation. You will note that at the revelation of the Torah at Mount Sinai (Exodus 19,3) G’d says to Moses: “so shall you say to the house of Yaakov and relate to the children of Yisrael.” The name Yaakov referred to the women, the word Yisrael to the men. [Perhaps the fact that Adam had described Eve as “bones of my bones and flesh of my flesh,” but not as “spirit of my spirit” (Genesis 2,23), is the reason that woman symbolizes primarily the physical part of the human being. Ed.] Isaiah 43, 22 had something similar in mind when he wrote: “But you have not worshipped Me, O Yaakov, that you should be weary of me O Israel.” He meant that while you Yaakov were concerned with your terrestrial matters you did not really worship Me (even if you paid lip-service). As to worshipping Me as “Yisrael,” you indicated that it was too wearisome for you.
When our Parshah commences by referring to Yaakov’s existence on earth by calling him Yaakov (twice in 47,28), this is in keeping with what we have explained. In 47,29 however, when the Torah commences to speak of “death” of the body, it switches to using the name “Yisrael” seeing that the death of a righteous person is but the necessary preamble to his taking his place in eternal life in the celestial spheres. Whenever preparations for death are described, including the very mention of the bed on which Yaakov lay sick, the Torah describes him as Yisrael. As soon as the Torah finishes describing his preparations for the life in the hereafter by blessing Joseph and his brothers, it reverts to the use of the name Yaakov. The Torah never describes Yaakov as having died. Only Yisrael is described as having died. The embalmers are described as embalming Yisrael (50,1). As soon as Yaakov had made the physical preparations for death, i.e. “he gathered in his feet to the bed,” the Torah calls him Yisrael again. As of that moment he had entered eternal life. When we find in 49,1 that the Torah refers to Yaakov suddenly again as Yaakov, the reason is that at that moment G’d withheld from him the visions of the redemption and what precedes it which he had intended to reveal to his sons. In other words, at that moment he had become primarily physical, his spiritual dimension having temporarily become subordinate. There is another instance where we could question why the Torah suddenly reverts to the use of the name Yaakov. This is in 48,3 where he explains to Joseph where and when he had his first communication from G’d, i.e. at Luz. The reason that the Torah calls him Yaakov at that point in our chapter is because he referred to a time in his life prior to his having the name Yisrael added to his regular name. in other words, we detect the following pattern. When the Torah indicates that Yaakov had not yet established mutual communication with G’d he is called Yaakov. When, even after he had established such communication, this channel of communication had been interrupted, he is also called Yaakov instead of Yisrael.
