The LORD our God is one LORD;
The LORD is our God, the LORD is one;
The LORD is our God, the LORD alone.
Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God. Isaiah 44:6
That they may know from the rising of the sun, and from the west, that there is none beside me. I am the LORD, and there is none else. Isaiah 45:6
Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me. I, even I, am the LORD; and beside me there is no savior. Isaiah 43:10-11.
Deuteronomy 6:4
4 Hear, O Israel: The LORD our God, the LORD is one
