According to Trinitarians, were/are some Jews Trinitarians? Who is this "Father" - the Creator spoken of throughout the Old Testament?

**The Old Testament identifies YHWH as "our Father", the Creator.** Is this ***"Father"***- the first person of the Trinity, God the Father? **Is he YHWH, the God of Israel?** Malachi 2:10 >Have we not all ***one Father***? Has not ***one God*** created us? Why do we deal treacherously with one another By profaning the covenant of the fathers? Isaiah 64:8 >But now, O **YHWH**, You are our ***Father***; We are the clay, and You our potter; And all we are the work of Your hand. Isaiah 63:16 >Doubtless You are our ***Father***, Though Abraham was ignorant of us, And Israel does not acknowledge us. **You, O *YHWH*, are our *Father***; Our Redeemer from Everlasting is Your name. Deuteronomy 32:6 >Do you thus deal with **YHWH**, O foolish and unwise people? Is He not your ***Father***, who bought you? Has He not made you and established you? John 8:41 >Then they said to Him, “We were not born of fornication; ***we have one Father—God***.” Jesus declares his Father to be the same God as the Jews, YHWH. John 8:54 >Jesus answered, “If I honor Myself, My honor is nothing. It is ***My Father*** who honors Me, of whom you say that **He is your God**." Paul appears to feel the same way. 2 Timothy 1:3 >I thank God, whom I serve with a pure conscience, **as my forefathers did**, as without ceasing I remember you in my prayers night and day, Ephesians 4:6 >one God and **Father** of all, who is above all, and through all, and in you all.
