Deuteronomy 4:35-39

“He showed you these things so you would know that the LORD is God and there is no other. He let you hear his voice from heaven so he could instruct you. He let you see his great fire here on earth so he could speak to you from it. Because he loved your ancestors, he chose to bless their descendants, and he personally brought you out of Egypt with a great display of power. He drove out nations far greater than you, so he could bring you in and give you their land as your special possession, as it is today. “So remember this and keep it firmly in mind: The LORD is God both in heaven and on earth, and there is no other.
