mdb take a look at vs 24.
Thus says the Lord, your Redeemer, And He who formed you from the womb: “I am the Lord, who makes all things, Who stretches out the heavens all alone, Who spreads abroad the earth by Myself;
Isaiah 44:24
God is the Redeemer: Isaiah 44:24; 48:17; 49:26; 63:16The Lord also says in Isaiah 44:24 that it is He who makes all things.
Jesus also made all things: Jn 1:3,14; Rom 11:36; 1 Cor 8:6; Col 1:15-17; Heb 1:8-10 (Ps 102:24-27); 2:10; Rev 4:11
I said, “O my God, Do not take me away in the midst of my days; Your years are throughout all generations. Of old You laid the foundation of the earth, And the heavens are the work of Your hands. They will perish, but You will endure; Yes, they will all grow old like a garment; Like a cloak You will change them, And they will be changed. But You are the same, And Your years will have no end.
Psalm 102:24-27
But to the Son He says:
“Your throne, O God, is forever and ever; A scepter of righteousness is the scepter of Your kingdom. You have loved righteousness and hated lawlessness; Therefore God, Your God, has anointed You With the oil of gladness more than Your companions.”
And:
“You, Lord, in the beginning laid the foundation of the earth, And the heavens are the work of Your hands. They will perish, but You remain; And they will all grow old like a garment; Like a cloak You will fold them up, And they will be changed. But You are the same, And Your years will not fail.”
Heb 1:8-12
You fail to see the OT reference to the Messiah. Or is it that you choose not to see it (whether it be in the book of Isaiah or some other context)? I would presume that you do not believe that Jesus Christ is yhwh and will try to explain any reference to His being yhwh away in order that your beliefs would not be proved wrong. Believe and be saved.
