מדרש אויף משלי 8:31

Why is it called "tevel" (an admixture)? For it is an admixture of all. For with all the lands, one possesses what the other does not, but Eretz Yisrael lacks nothing, as it is written (Devarim 8:9) "a land where not in constraint shall you eat bread. You shall lack nothing in it."

Variantly: Why is it called "tevel"? Because of the "tavlin" ("seasoning") in its midst. Which "tavlin" is in it? — Torah, viz. (Eichah 2:9) "Among the nations there is no Torah" — whence it is seen that the home of Torah is Eretz Yisrael.

[2] Another interpretation: And Judah approached him (Joseph), as it is said in scriptures, "and I will be with him in trouble, and I will deliver him and honor him" (Psalms 91:15). So too did the Almighty increase the Torah. Whoever seeks to engage in Torah study, the Torah plays with him, as it is said, "playing in the inhabited world" (Proverbs 8:31). There is no greater scholar than Solomon, and regarding one who sought to abolish the letter Yud (י) from the Torah, see what happened to him. When Solomon became king and sat on his throne and reviewed the Torah, it is written, "And it will be when he sits on the throne of his kingdom, he shall write for himself a copy of this Torah" (Deuteronomy 17:18). When he saw that he had not increased wealth or women, he said, "I will multiply wives for myself and gold and horses" (Deuteronomy 17:17). How many women did he have? As it is said, "And he had seven hundred wives, princesses, and three hundred concubines" (I Kings 11:3). How many horses did he have? As it is said, "And Solomon had forty thousand stalls of horses" (Ibid, 4:26). And how much silver and gold did he have? As it is said, "The king made silver and gold in Jerusalem like stones" (II Chronicles 1:15). "Immediately, the Torah ascended before the Holy One, blessed be He, and said to Him: 'Master of the Universe, why am I still waiting here on earth? If King Solomon, the wisest of the wise, annulled me, who will uphold me?' The Holy One, blessed be He, replied: 'Your life is worth a thousand times the life of Solomon, for even if all the sages were to nullify you, the letter yud (י) in the Torah cannot be nullified. Whatever is nullified, the yud is never nullified. I will treat it as if the entire Torah was nullified because of it, as it is said: 'And the Lord said to Solomon: "Since this has been your attitude and you have not kept my covenant and my decrees" (1 Kings 11:11). The Torah that is referred to as 'this' (זאת), as it is said: 'And this is the Torah' (Deuteronomy 4:44). It is said that it was 'with him' (Solomon), as it is said: 'And it shall be with him and he shall read it' (Deuteronomy 17:19). And you (Torah) have caused the tearing apart of the kingdom from him, as it is said: 'I will tear the kingdom away from you [and give it to one of your servants.]' (I Kings 11:11)[edit. Hebrew text says " shem " 11:15]. Why? Because you played games in his world."
