Deuteronomy 4:35-39

He showed you things so you would know that the LORD is God, and there is no other God besides him. He spoke to you from heaven to teach you. He showed you his great fire on earth, and you heard him speak from the fire. Because the LORD loved your ancestors, he chose you, their descendants, and he brought you out of Egypt himself by his great strength. He forced nations out of their land ahead of you, nations that were bigger and stronger than you were. The LORD did this so he could bring you into their land and give it to you as your own, and this land is yours today. Know and believe today that the LORD is God. He is God in heaven above and on the earth below. There is no other god!
