Rabbi Hanina holds that the Jewish people are subject to a constellation's influence, while Rabbi Yohanan and Rav both derive from Tanach that the Jewish people are not subject to astral influence—the nations are affected by the heavens, but not Israel.
אִיתְּמַר, רַבִּי חֲנִינָא אוֹמֵר: מַזָּל מַחְכִּים, מַזָּל מַעֲשִׁיר, וְיֵשׁ מַזָּל לְיִשְׂרָאֵל. רַבִּי יוֹחָנָן אָמַר: אֵין מַזָּל לְיִשְׂרָאֵל. וְאַזְדָּא רַבִּי יוֹחָנָן לְטַעְמֵיהּ, דְּאָמַר רַבִּי יוֹחָנָן: מִנַּיִין שֶׁאֵין מַזָּל לְיִשְׂרָאֵל? שֶׁנֶּאֱמַר: ״כֹּה אָמַר ה׳ אֶל דֶּרֶךְ הַגּוֹיִם אַל תִּלְמָדוּ וּמֵאוֹתוֹת הַשָּׁמַיִם אַל תֵּחָתּוּ כִּי יֵחַתּוּ הַגּוֹיִם מֵהֵמָּה״ — הֵם יֵחַתּוּ, וְלֹא יִשְׂרָאֵל. וְאַף רַב סָבַר אֵין מַזָּל לְיִשְׂרָאֵל, דְּאָמַר רַב יְהוּדָה אָמַר רַב: מִנַּיִין שֶׁאֵין מַזָּל לְיִשְׂרָאֵל? — שֶׁנֶּאֱמַר: ״וַיּוֹצֵא אוֹתוֹ הַחוּצָה״, אָמַר אַבְרָהָם לִפְנֵי הַקָּדוֹשׁ בָּרוּךְ הוּא: רִבּוֹנוֹ שֶׁל עוֹלָם, ״בֶן בֵּיתִי יוֹרֵשׁ אוֹתִי״, אָמַר לוֹ: לָאו — ״כִּי אִם אֲשֶׁר יֵצֵא מִמֵּעֶיךָ״.
It was stated that Rabbi Ḥanina says: A constellation makes one wise and a constellation makes one wealthy, and there is a constellation for the Jewish people that influences them. Rabbi Yoḥanan said: There is no constellation for the Jewish people that influences them. The Jewish people are not subject to the influence of astrology. And Rabbi Yoḥanan follows his own reasoning, as Rabbi Yoḥanan said: From where is it derived that there is no constellation for the Jewish people? As it is stated: “Thus said the Lord: Learn not the way of the nations, and be not dismayed at the signs of heaven; for the nations are dismayed at them” (Jeremiah 10:2). The nations will be dismayed by them, but not the Jewish people. And Rav also holds that there is no constellation for the Jewish people, as Rav Yehuda said that Rav said: From where is it derived that there is no constellation for the Jewish people? As it is stated with regard to Abraham: “And He brought him outside, and said: Look now toward heaven, and count the stars, if you are able to count them; and He said unto him: So shall your offspring be” (Genesis 15:5). The Sages derived from this that Abraham said before the Holy One, Blessed be He: Master of the Universe, “Behold, You have given me no offspring, and one born in my house is to be my heir” (Genesis 15:3). The Holy One, Blessed be He, said to him: No. “And, behold, the word of the Lord came to him, saying: This man shall not be your heir; rather, one that will come forth from your own innards shall be your heir” (Genesis 15:4).
