וְנָתַתִּ֤י לְךָ֙ אוֹצְר֣וֹת חֹ֔שֶׁךְ וּמַטְמֻנֵ֖י מִסְתָּרִ֑ים לְמַ֣עַן תֵּדַ֗ע כִּֽי־אֲנִ֧י יְהוָ֛ה הַקּוֹרֵ֥א בְשִׁמְךָ֖ אֱלֹהֵ֥י יִשְׂרָאֵֽל׃
Aku akan memberikan kepadamu harta yang tersimpan di tempat-tempat gelap dan kekayaan yang terpendam di tempat-tempat tersembunyi, supaya engkau tahu bahwa Akulah Yang Mahakekal, yang memanggil engkau dengan namamu, Allah Israel.

An old woman in the houseùa treasure (סימא) in the house. A good treasure. The Targum translates ומטמוני מסתרים, “secret hidden things” (Yeshayahu 45:3) as סימא דמטמרן.
Malbim
The pathway I have cleared in explaining this book leads the reader directly to a city of habitation (Psalms 107:7), bringing him to a place of rest and inheritance (Deuteronomy 12:9), where he will discover hidden treasures (Isaiah 45:3); for a wise word is a precious jewel (Proverbs 20:15).
Malbim
And now that I have made all this known to you; and after giving thanks to God for the mercy He has bestowed upon me (Psalms 117:2) by enlightening me and imparting it all to me; and after praying that He may guide me in the paths of righteousness (Psalms 23:3) and teach me His ways for His Name's sake. (Isaiah 2:3) I will now set off ahead of you and make the crooked places straight (Isaiah 45:2), I will bring you treasures from the darkness, and the hidden riches of secret places (Isaiah 45:3). May the Lord accomplish His purpose for me, forsaking not the work of my hands (Psalms 138:8). Open my eyes, that I might perceive the wonders of Your Torah. (Psalms 119:18).
