As I suspected ...
If its not IN the text then you are hallucinating your theology ONTO the text. And given your use of the Abraham passage ... that is exactly what you are doing. There is no mention of a NT church separate and distinct from the nation of Israel.
So YHWH (that is the name translated LORD here) promises a blessing to “all the families of the earth”. That includes the “family” you call the church.
Like I said ... you are reading what you want into the text of Scripture ... it says nothing of a NT church as a separate and distinct people of God from the Jews.
What you need to go find is an OT passage that predicts the old covenant being replaced by a new covenant whereby both Jews and Gentile are members by way of regeneration.
As far as the Daniel citation ... I agree with you 100%.
The Trinity is not “in the text”. The Old Testament is not replaced by the New Testament. The New Testament is the fulfillment of the Old Testament. But, not to worry, there will be plenty of time to sort this all out during the Millennial Kingdom. Oh! Wait! “Millennial Kingdom” is not in the text! Sorry! ;-)
