Midrash sa Isaias 40:17: Bamidbar Rabbah, Midrash Tanchuma, Midrash Tanchuma Buber & Shir HaShirim Rabbah

Another matter: “The Lord spoke to Moses in the wilderness of Sinai” – that is what the verse said: “Your navel is a moon-shaped goblet” (Song of Songs 7:3); it is speaking of the Sanhedrin that was situated in the Chamber of Hewn Stone and is analogized to the navel. Why is it analogized to the navel? It is, that just as this navel is situated in the middle of the body, so, the Sanhedrin is situated in the middle of the Temple. “May it not lack blended wine [al yeḥsar hamazeg]” (Song of Songs 7:3) – what is “al yeḥsar hamazeg”? That there were never less than one-third of them. “Al yeḥsar hamazeg” – one who dilutes [mozeg] properly, dilutes with one-third of the cup wine and two parts water. So, the Sanhedrin would convene there from the daily morning offering until the daily afternoon offering, and no one of them would leave to tend to his own affairs. What would they do if one of them sought to leave? He would count; if there were twenty-three there, he would leave, if not, he would not leave.⁶The Sanhedrin had seventy members. Twenty-three is just under one third. Why? It is because it is written: “May it not lack blended wine [al yeḥsar hamazeg]” that one-third of them were never missing. Therefore, al yeḥsar hamazeg.
“Your belly is a pile of wheat” (Song of Songs 7:3) – Israel was likened to a pile of wheat; just as this wheat enters the storehouse by number, so, the Holy One blessed be He said that Israel should be counted at all times.⁷This is a sign of importance. That is why it is stated: “Your belly is a pile of wheat.” But straw and stubble are not counted and not measured; so, the nations of the world were likened to straw and stubble, as it is stated: “Like stubble before the wind” (Psalms 83:14), and likewise: “The house of Esau to stubble” (Obadiah 1:18). Why? It is because the Holy One blessed be He derives no pleasure from them, as it is stated: “All the nations are as nothing before Him” (Isaiah 40:17). But Israel, the Holy One blessed be He derives pleasure from them; they recite Shema, pray, and bless the name of the King of kings, the Holy One blessed be He, every day. That is why they are counted at all times and that is why they were likened to wheat. “Your belly is a pile of wheat.”

And Joseph was brought down into Egypt (Gen. 39:1). May it please our master to teach us whether one may recite the Havdalah prayer at the expiration of the Sabbath with a light used by an idolater? Thus did our masters teach us: It is forbidden to recite the Havdalah prayer with a light used by an idolater. Why? Because it (the light) does not rest from its work.⁶It remains a light used for idolatry. B. Berakhot 53b. Furthermore, if you did recite the Havdalah prayer with a light used by an idolater, you would be treating the idolater as though he deserved to be highly regarded, and Scripture states: All the nations are as nothing before Him (Isa. 40:17).

(Deut. 12:29:) WHEN THE LORD GOD HAS CUT OFF THE GENTILES. A parable: To what is the matter comparable? To a king who planted a vineyard within his field, but within <that field> were great cedars and thorns.⁵Tanh., Deut. 4:9. The king went and cut down the cedars and left the thorns. His servants said to him: Our Lord King, the thorns, which catch our clothes, you have left <standing>; but you have cut down the cedars! He said to them: If I had left the cedars and cut down the thornbushes, how should I have {decreed} [fenced in] my vineyard. So also Israel is the vineyard of the Holy One, as stated (in Is. 5:7): FOR THE VINEYARD OF THE LORD OF HOSTS IS THE HOUSE OF ISRAEL. He brought Israel into the land and cut down the cedars that were in it, as stated (in Amos 2:9): YET I DESTROYED THE AMORITES [BEFORE YOU, WHOSE STATURE WAS LIKE THE CEDARS IN HEIGHT]; but he left their children and their children's children so that Israel would observe the Torah, as stated (in Jud. 3:1): NOW THESE ARE THE NATIONS WHICH THE LORD LEFT TO TEST ISRAEL. So when the vineyard stands in its place in the service of the Torah, THEN (according to Is. 33:12) THE PEOPLES SHALL BECOME BURNINGS OF LIME, THORNS CUT DOWN <THAT ARE BURNED IN THE FIRE>. It is also written (in Is. 40:17): ALL THE NATIONS ARE AS NOTHING BEFORE HIM. Look at how many hosts⁶Gk.: ochloi. Pharaoh sent out after Israel! When Israel saw them, they were terrified before them and said: Who can stand against these? The Holy One said to them: By your lives, all these are as unimportant before me as <if they were> [only] a single horse, as stated (in Exod. 15:19): WHEN THE HORSE (in the singular) OF PHARAOH CAME; they all died in a single breath (rt.: NShP), as stated (in Exod. 15:10): YOU BLEW (rt.: NShP) WITH YOUR WIND, <AND THE SEA COVERED THEM>. Similarly Gog and Magog are going to come against Israel, but the Holy One will carry out judgments against them (literally: against him), as stated (in Ezek. 38:22): I WILL ENTER INTO JUDGMENT AGAINST HIM WITH PESTILENCE AND WITH BLOOD…. At that time (according to Ezek. 38:23): SO I WILL BE MAGNIFIED, BE SANCTIFIED, AND BE MADE KNOWN BEFORE THE EYES OF MANY {PEOPLES} [NATIONS]; AND THEY SHALL KNOW THAT I AM THE LORD.
