You shall not have the gods of others in My presence. גלֹ֣א יִֽהְיֶ֣ה־לְךָ֩ אֱלֹהִ֨ים אֲחֵרִ֜ים עַל־פָּנַ֗י:
Shemot (Exodus) 20:3

Concerning all that I have said to you you shall beware, and the name of the gods of others you shall not mention; it shall not be heard through your mouth. יגוּבְכֹ֛ל אֲשֶׁר־אָמַ֥רְתִּי אֲלֵיכֶ֖ם תִּשָּׁמֵ֑רוּ וְשֵׁ֨ם אֱלֹהִ֤ים אֲחֵרִים֙ לֹ֣א תַזְכִּ֔ירוּ לֹ֥א יִשָּׁמַ֖ע עַל־פִּֽיךָ:
Shemot (Exodus) 23:13

You have been shown, in order to know that the Lord He is God; there is none else besides Him. להאַתָּה֙ הָרְאֵ֣תָ לָדַ֔עַת כִּ֥י יְהֹוָ֖ה ה֣וּא הָֽאֱלֹהִ֑ים אֵ֥ין ע֖וֹד מִלְּבַדּֽוֹ:
Devarim (Deuteronomy) 4:35

But the prophet who intentionally speaks a word in My name, which I did not command him to speak, or who speaks in the name of other gods, that prophet shall die. כאַ֣ךְ הַנָּבִ֡יא אֲשֶׁ֣ר יָזִיד֩ לְדַבֵּ֨ר דָּבָ֜ר בִּשְׁמִ֗י אֵ֣ת אֲשֶׁ֤ר לֹֽא־צִוִּיתִיו֙ לְדַבֵּ֔ר וַֽאֲשֶׁ֣ר יְדַבֵּ֔ר בְּשֵׁ֖ם אֱלֹהִ֣ים אֲחֵרִ֑ים וּמֵ֖ת הַנָּבִ֥יא הַהֽוּא:
Devarim (Deuteronomy) 18:20

Remember the first things of old, that I am God and there is no other; I am God and there is none like Me. טזִכְר֥וּ רִֽאשֹׁנ֖וֹת מֵֽעוֹלָ֑ם כִּ֣י אָֽנֹכִ֥י אֵל֙ וְאֵ֣ין ע֔וֹד אֱלֹהִ֖ים וְאֶ֥פֶס כָּמֽוֹנִי:
Yeshayahu (Isaiah) 46:9

I am the Lord, that is My Name; and My glory I will not give to another, nor My praise to the graven images. חאֲנִ֥י יְהֹוָ֖ה ה֣וּא שְׁמִ֑י וּכְבוֹדִי֙ לְאַחֵ֣ר לֹֽא־אֶתֵּ֔ן וּתְהִלָּתִ֖י לַפְּסִילִֽים:
Yeshayahu (Isaiah) 42:8

Hearken to Me, O Jacob, and Israel, who was called by Me, I am He, I am first, yea I am last. יבשְׁמַ֚ע אֵלַי֙ יַֽעֲקֹ֔ב וְיִשְׂרָאֵ֖ל מְקֹֽרָאִ֑י אֲנִי־הוּא֙ אֲנִ֣י רִאשׁ֔וֹן אַ֖ף אֲנִ֥י אַֽחֲרֽוֹן:
Yeshayahu (Isaiah)48:12
