G-D said so numerous times. G-d said don't trust anyone but him. What is unclear? Torah Sources - Jewish Israel TORAH SOURCES: Shemot (Exodus) 20:2-3 "I am the L-rd thy God, who brought thee out of the land of Egypt, out of the house of bondage. Thou shalt have no other gods before Me" ("You shall not recognize the gods of others in My presense"). Shemot (Exodus) 20:18 "One who brings offerings to the gods shall be destroyed - only to Hashem alone!" Bamidbar (Numbers) 23:19 G-d is not a man that He should lie, nor a son of man, that He should relent. Devarim (Deuteronomy) 4:15 Take good heed of yourselves, for you saw no manner of form on that day when G-d spoke to you at Horeb... Devarim (Deuteronomy) 4:35 Unto you it was shown, that you might know, that the L-rd is G-d, there is none else besides Him. Devarim (Deuteronomy) 4:39 Know this day, and lay it in your heart, that the L-rd is G-d, in the heavens above and on the earth below, there is none else. Devarim (Deuteronomy) 6:4 "Hear, O Israel: The L-rd is our G-d, the L-rd is One". Devarim (Deuteronomy) 11:16-17 Be careful lest your heart is seduced, that you turn away and serve other gods and that you bow down to them. And then the L-rds anger will burn against you and He will shut up the heavens and there will be no rain and the land will not yield its produce. You will be quickly cut off from the good land that the L-rd is giving to you. Devarim (Deuteronomy) 13:1-2 "Everything I command you that you shall be careful to do it. You shall neither add to it, nor subtract from it. If there arise among you a prophet, or a dreamer, and he gives you a sign or a miracle. And the sign or miracle comes to pass, and he calls on you, saying, Let us go after other gods, whom you have not known, and let us worship them. You shall not listen to that prophet or dreamer. For G-d is testing you, to see whether you love the L-rd your G-d with all your heart and with all your soul" THE PROPHETS Yirmiyahu (Jeremiah) 16:19-20 "To You the nations will come from the distant parts of the land" and they will confess, 'Our ancestors inherited falsehood, futility that has no purpose. Can a man make a god? The man not being a god?'" Yeshayahu (Isaiah) 40:18 "To whom can you liken God? Or what likeness can you compare to him?" Yeshayahu (Isaiah) 42:8 "I am G-d; that is My Name. I will not grant My honor to anyone else or My glory to idols." Yeshayahu (Isaiah) 43:10 "You are My witnesses," says G-d, "and My servant whom I chose," in order that you know and believe Me, and understand that I am He; before Me no god was formed and after Me none shall be." Yeshayahu (Isaiah) 43:11 " I am G-d, I alone. There is no Savior besides Me." Yeshayahu (Isaiah) 45:5 "Thus says G-d, the King of Israel and its Redeemer, the L-rd of Hosts, "I am the first and I am the last, and there is no god besides Me." Yeshayahu (Isaiah) 45:22 "Turn to Me and be saved, all the ends of the earth, for I am G-d, and there is no other." Yeshayahu (Isaiah) 46:5 "To whom can you liken Me and whom can you declare My equal? To what can you compare Me that we should seem similar?"
