The bible doesn't say there are many Gods.
"But you shall destory their altars, break their sacred pillars, and cut down their wooden images (for you shall worship no other god, for the LORD whose name is Jealous, is a jealous God)..." (Exodus 34:13-14).
“And I fell at his feet to worship him. But he said to me, 'See that you do not do that! I am your fellow servant, and of your brethren who have the testimony of Jesus. Worship God! For the testimony of Jesus is the spirit of prophecy.'” (Revelation 19:10).
"To you it was shown, that you might know that the LORD Himself is God; there is none other besides Him....Therefore know this day, and consider it in your heart, that the LORD Himself is God in heaven above and on the earth beneath; there is no other." (Deuteronomy 4:35-39).
"'Now see that I, even I, am He, and there is no God besides Me; I kill and I make alive; I wound and I heal; nor is there any who can deliver from My hand." (Deuteronomy 32:39).
"No one is holy like the LORD, for there is none besides You, nor is there any rock like our God." (1 Samuel 2:2).
"Therefore You are great, O Lord GOD. For there is none like You, nor is there any God besides You, according to all that we have heard with our ears." (2 Samuel 7:22).
"And may these words of mine, with which I have made supplication before the LORD, be near the LORD our God day and night, that He may maintain the cause of His servant and the cause of His people Israel, as each day may require, that all the peoples of the earth may know that the LORD is God; there is no other." (1 Kings 8:59-60).
"Then Hezekiah prayed before the LORD, and said: 'O LORD God of Israel, the One who dwells between the cherubim, You are God, You alone, of all the kingdoms of the earth. You have made heaven and earth. Incline Your ear, O LORD, and hear; open Your eyes, O LORD, and see; and hear the words of Sennacherib, which he has sent to reproach the living God. Truly, LORD, the kings of Assyria have laid waste the nations and their lands, and have cast their gods into the fire; for they were not gods, but the work of men’s hands - wood and stone. Therefore they destroyed them. Now therefore, O LORD our God, I pray, save us from his hand, that all the kingdoms of the earth may know that You are the LORD God, You alone.'" (2 Kings 19:15-19).
"Yet I am the LORD your God ever since the land of Egypt, and you shall know no God but Me; for there is no savior besides Me." (Hosea 13:4).
"Inasmuch as there is none like You, O LORD (You are great, and Your name is great in might), who would not fear You, O King of the nations?...But the LORD is the true God; He is the living God and the everlasting King. At His wrath the earth will tremble, and the nations will not be able to endure His indignation. Thus you shall say to them: 'The gods that have not made the heavens and the earth shall perish from the earth and from under these heavens.'...Every metalsmith is put to shame by an image; for his molded image is falsehood, and there is no breath in them. They are futile, a work of errors; in the time of their punishment they shall perish. The Portion of Jacob is not like them, for He is the Maker of all things, and Israel is the tribe of His inheritance; the LORD of hosts is His name." (Jeremiah 10:6-16).
