Read Jamesh's post again. Who is the Lord your Redeemer Isaiah 44:24? Lord translates from YHWH.
Let's go to Isaiah 44:6 and we see 2/3 of the Trinity.
Since explicit trumps implicit, I submit the following. Below is Isaiah 44:6 were two individuals are identified as YHWH, = YHWH the King of Israel and YHWH the Lord of Host, both claiming to be First and Last and claiming singularity by addressing themselves as “Me”.
Isaiah 44:6 “Thus says the Lord, the King of Israel, And His Redeemer, the Lord of host, :I am the First and I am the Last; Besides Me there is no God. {NKJV}
In the original “Lord” is translated from YHWH therefore this verse reads. “Thus says YHWH, the King of Israel, and His Redeemer, YHWH, Lord of host, I am the First and I am the Last, Besides Me the is no God.
Thus says the Lord, the King of Israel,
כה thus אמר he said יהוה: Yahweh מלך king of ישׂראל : Israel
And his Redeemer, the Lord of hosts:
ו: and הוא his/him גאל redeemer יהוה : Yahweh of-- צבא hosts
‘I am the First and I am the Last;
אני I-- ראשׁון first-- ו: and-- אני I-- אחרון: last—
Besides Me there is no God
בלעדי: without-- אני me-- אין does not exist-- אלהים : God
