ישעיהו מ:כח פירוש: רש״י ואבן עזרא

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.

הלא ידעת Hast thou not known by common sense; for he who is thinking can attain a knowledge of his Creator by convincing proofs.

אם לא שמעת Hast thou not heard, and learnt from others, who have studied.⁶⁰See Note 49.
