כוה־אמר יהוה למשיחו לכורש אשר־החזקתי בימינו לרד־לפניו גואים ומתני מלכים אפתח לפתח לפניו דלתים ושערים לוא יסגרו (DDS)

οὕτως λέγει κύριος ὁ θεὸς τῷ χριστῷ μου Κύρῳ οὗ ἐκράτησα τῆς δεξιᾶς ἐπακοῦσαι ἔμπροσθεν αὐτοῦ ἔθνη καὶ ἰσχὺν βασιλέων διαρρήξω ἀνοίξω ἔμπροσθεν αὐτοῦ θύρας καὶ πόλεις οὐ συγκλεισθήσονται (LXX)

This is a very complex and controversial verse.

כוה : οὕτως
אמר : λέγει
יהוה: διῆ ὑή
ל משיח ו: τῷ χριστῷ αὐτῶ
ל כורש : τῷ Κύρῳ
אשר: ὅστε
ה חזקת י :ἧ ἴσχυσα μοι 'to be strong'
ב ימינ ו : ἐν δεξιᾷ αὐτοῦ
ל רד : τῷ κρατῆσαι 'conquer, prevail, get the upper hand'
לפניו :ἐναντίον αὐτοῦ
גואים : Σκύθης, Σκυθῶν (γαιῶν) 'Scythians
ו מתנ י : καὶ ὀσφῦν μοι 'loins'
מלכים : ἀναξῶν 'Kings'
אפתח : αἴ πτύσσω, ἀμφί-πτύσσω 'unfold, unfold on both sides
ל פתח : τῷ πτύξαι 'fold, double up
לפניו : ἐναντίον αὐτοῦ
דלתים : δικλίς, δικλίδος 'double-folding doors
ו שערים :καὶ θυράων 'doors'
לוא : οὖ
יסגר ו : ἐγκλίνω, εγκλιθηση 'bend in or inwards.

Perhaps this is describing an actual structure with double-doors else its being abstract.

Thus said the LORD to Cyrus, His anointed one -- Whose right hand He has grasped, Treading down nations before him, Ungirding the loins of kings, Opening doors before him And letting no gate stay shut: (Isa. 45:1 TNK)

I assume Cyrus annoited one (Moshiach/Messiah) is why it's controversial.

‎כֹּה־אָמַ֣ר יְהוָה֘ לִמְשִׁיחוֹ֘ לְכ֣וֹרֶשׁ אֲשֶׁר־הֶחֱזַ֣קְתִּי בִֽימִינ֗וֹ לְרַד־לְפָנָיו֙ גּוֹיִ֔ם וּמָתְנֵ֥י מְלָכִ֖ים אֲפַתֵּ֑חַ לִפְתֹּ֤חַ לְפָנָיו֙ דְּלָתַ֔יִם וּשְׁעָרִ֖ים לֹ֥א (Isa. 45:1 WTT)

It is controversial because it debunks Messianic Judaism and Christianity.

My hero, Dr. Lisbeth S. Fried, has a good article on this.

Somehow they have prevented copying excerpts of the document which is 22 pages long.

Dr. Fried argues that

Deutero-Isaiah was convinced that Cyrus was in actuality the genuine Judean king, i.e., YHWH's anointed, his Messiah, because Cyrus was able to do what a legitimate king must do: he brought back the status quo ante. He rebuilt the temple, ordered the temple vessels replaced in it, and permitted the Jews to return to worship their God in Zion restored.

I have only skimmed the article, but it seems excellent.
