Isaiah records his vision of the Jehovah God of the OT, The King, The Lord of Hosts, in Isa. 6:1-5.
"In the year that king Uzziah died I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple.
Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly.
And one cried unto another, and said, Holy, holy, holy, is the Lord of hosts: the whole earth is full of his glory.
And the posts of the door moved at the voice of him that cried, and the house was filled with smoke.
Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the Lord of hosts."
The apostle John tells us who Isaiah seen. John 12:37-43
"But though he had done so many miracles before them, yet they believed not on him:
That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?
Therefore they could not believe, because that Esaias said again,
He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
These things said Esaias, when he saw his glory, and spake of him.
Nevertheless among the chief rulers also many believed on him; but because of the Pharisees they did not confess him, lest they should be put out of the synagogue:
For they loved the praise of men more than the praise of God."
Isaiah seen Jehovah God, The Lord of Hosts, and it was a vision of the pre-incarnate Jesus Christ sitting on the Throne, "The King, The Lord of Hosts."
