A Brief Exposition of New Church Doctrine # 36
36. That a trinity of Gods is contrary to Holy Scripture is well known, for it is written:
Am not I Jehovah? and there is no God else besides Me; a just God and a Saviour there is none besides Me.Isaiah 45:21-22.
I, Jehovah, am thy God... and thou shalt acknowledge no God besides Me for there is no Saviour besides Me. Hosea 13:4.
Thus saith Jehovah the King of Israel, and His Redeemer, Jehovah Zebaoth: I am the First and I am the Last, and besides Me there is no God.Isaiah 44:6.
Jehovah Zebaoth is His Name, and thy Redeemer the Holy One of Israel; the God of the whole earth shall He be called.Isaiah 54:5.
In that day... Jehovah shall be King over all the earth; in that day there shall be one Jehovah and His Name One. Zechariah 14:9.
There are also many more such passages.
Isaiah 45:21-22
21
Declare and present it. Yes, let them take counsel together. Who has shown this from ancient time? Who has declared it of old? Haven't I, Yahweh? There is no other God besides me, a just God and a Savior; There is no one besides me.
22
"Look to me, and be saved, all the ends of the earth; for I am God, and there is no other.
