No, Tanakh reveals only one being as God.
Wrong. There's a second person.
Here He is called the Glory of the Lord:
Exodus 16:7
and in the morning you will see
the glory of the Lord, because
he has heard your grumbling against him. Who are we, that you should grumble against us?”
Isaiah 48:16
Come ye near unto me, hear ye this; I have not spoken in secret from the beginning; from the time that it was, there am I: and now
the Lord GOD, and his Spirit, hath sent me.
Isaiah 63:9-10
9In all their affliction he was afflicted, and
the angel of his presence saved them: in his love and in his pity he redeemed them; and he bare them, and carried them all the days of old.
10But they rebelled, and vexed
his holy Spirit: therefore he was turned to be their enemy, and he fought against them.
