In old testament there are so many verses that God is one like if we read (Exodus 20:3) ”˜'you must not worship any other God except me.'' Here God command Israeli's not to worship any other god. Then in (Isaiah 45:18) says that The Lord is God. He made the skies and the earth. He put the earth in its place. He did not want the earth to be empty when he made it. He created it to be living on. I am the Lord. There is no other God.
