הֲל֨וֹא יָדַ֜עְתָּ אִם־לֹ֣א שָׁמַ֗עְתָּ אֱלֹהֵ֨י עוֹלָ֤ם ׀ יְהוָה֙ בּוֹרֵא֙ קְצ֣וֹת הָאָ֔רֶץ לֹ֥א יִיעַ֖ף וְלֹ֣א יִיגָ֑ע אֵ֥ין חֵ֖קֶר לִתְבוּנָתֽוֹ׃
Hindi mo ba nalalaman? Hindi mo ba narinig? Ang walang-hanggang Diyos, ang Walang-Hanggan, ang Lumikha ng mga dulo ng lupa, ay hindi nanghihina ni napapagod; walang makaaarok sa Kanyang karunungan.
Tze'enah Ure'enah
“Have you not known? Have you not heard, etc.” [40:28]. Why should you Israel say that I have not watched over you and have not meted out judgment to the nations that tormented you greatly? You should know from your own understanding or if your understanding is inadequate, then you have heard it, in any event, from sages who told you that God created the world and He is the judge of the whole world. He created it with truth and He judges it properly. How can you say that I do not do justice? If you want to say that I am sometimes tired and cannot dispense justice, therefore the verse says here, “He never grows tired or weary” [40:28]. That is to say, He is not tired. He created the whole world with his strength. If you would say, since the Holy One has such great strength, why does He see that we are in exile for so long and He does not judge the nations? Concerning this the verse says here, “His wisdom cannot be fathomed” [40:28]. That is to say, we cannot understand His wisdom. However, the Holy One knows well why He does this.2Radak, Isaiah, 40:28.
Rashi
the Creator of the ends of the earth...there is no fathoming His understanding And One who has such strength and such wisdom—He knows the thoughts. Why does He delay your benefit, only to terminate the transgression and to expiate the sin through afflictions.
Ibn Ezra
הלא ידעת Hast thou not known by common sense; for he who is thinking can attain a knowledge of his Creator by convincing proofs.
