Sorry no as I never stated the Hebrew race is saved. You read that idea into my words as you read your theology into scripture.
Kindly quote what it is you are supposed to be responding to so it may be determined wether your comment actually address what was posted and actually provide a rebuttal
First you are reading your theology into the passage.
Rather an unlimited atonement is in view as the writer just stated
Hebrews 2:9 (LEB) — 9 but we see Jesus, for a short time made lower than the angels, because of the suffering of death crowned with glory and honor, so that apart from God
he might taste death on behalf of everyone.
Second the text before us is not Gal 3:29 but
Hebrews 2:14–16 (KJV 1900) — 14 Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; 15 And deliver them who through fear of death were all their lifetime subject to bondage. 16 For verily he took not on him the nature of angels; but he took on him the seed of Abraham.
Which is speaking of the incarnation
And it is flesh and blood humanity Christ took upon himself; in particular the humanity seen in the Jewish people
And as for seed of Abraham
2 Chron 20:7Art not thou our God, who didst drive out the inhabitants of this land before thy people Israel, and gavest it to
the seed of Abraham thy friend for ever?
Isa 41:8But thou, Israel, art my servant, Jacob whom I have chosen,
The seed of Abraham my friend.
Jer 33:26Then will I cast away the seed of Jacob, and David my servant, so that I will not take any of his seed to be rulers
over the seed of Abraham, Isaac, and Jacob: for I will cause their captivity to return, and have mercy on them.
Rom 9:7Neither, because they are
the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.
Rom 11:1I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of
the seed of Abraham, of the tribe of Benjamin.
2 Cor 11:22Are they Hebrews? so am I. Are they Israelites? so am I.
Are they the seed of Abraham? so am I.
Heb 2:16For verily he took not on him the nature of angels; but he took on him
the seed of Abraham.
It seems to me you never address the point raised that it is the incarnation which is in view that is Christ taking on the nature of man
