ציטירנדיקער פּירוש אויף בראשית 29:11

Let him kiss me with the kisses of his mouth. She recites this song with her mouth in her exile and in her widowhood, “If only King Shlomo would kiss me with the kisses of his mouth as of yore,”⁷“With the kisses of his mouth” is obviously superfluous, therefore Rashi explains that it refers to the days of yore. (Sifsei Chachomim) because in some places they kiss on the back of the hand or on the shoulder, “but I desire and wish that he behave with me as his original behavior, like a bridegroom with a bride, mouth to mouth.”⁸If it were not mouth to mouth the verb נשק [=kiss] would be followed with a lamed as in Bereishis 27:26 and Ibid. 29:11, and in many other places. (Sifsei Chachomim)

We must therefore look for some meaning beyond the mere words of the verse. Esau was aware of Jacob's' departure and of its nature, i.e. that he thereby fulfilled both a commandment by his father and mother and the commandment to look for a wife. Knowing that Isaac had blessed Jacob to complete his undertaking successfully, Esau did not bother to pursue Jacob, realising that under such circumstances he would not succeed. Although Esau is reputed to have sent his eldest son Eliphaz to catch up with Jacob and to kill him (according to Rashi on Genesis 29,11), it is possible that he merely wanted to test his ability to vanquish Jacob on his journey. This scenario may have been re-enacted when the descendants of Esau (Amalek) attacked the Israelites after the latter had crossed the sea of reeds. Esau considered his son's ability to pursue Jacob successfully as greater than his own ability to do so.

The number of Levites (of whom Scripture tells specifically as singing hymns) is eight. They were: אסף, הימן, ידותן ,איתן האזרחי,; this makes four. Add Levi, who is referred to here as בן “son;” this makes five; then there is the one called על הגיתית, a reference to the family of Gattit a song offered by that family who hosted the Holy Ark. (compare Chronicles I 13,13). This gives us six. Add the sons of Korach; this makes seven. Finally, there are the “sons” of Moses giving us a grand total of eight such “singers,” or better: “composers of songs and hymns” who were all Levites. These eight people between them used eight musical instruments. The instruments are known as:
1) נגינות (Psalms. 4,1).
2) מחלת, (Psalms. 53,1).
3) עלמות שיר (Psalms. 46,1).
4) משאת (Chronicles I 15,22).
5) נחילות (Psalms .5,1).
6) שושנים, (Psalms. 45,1).
7) גתית, (Psalms. 8,1).
8) שמינית, (Psalms 6,1).
