Yea, thou heardest not; yea, thou knewest not; the same thing is repeated again and again, because this was so illustrious a proof of the infinite power and providence of the God of Israel, and so clear and full a discovery of the vanity of idols. Yea, from that time that thine ear was not opened; Heb. yea, from then (of which phrase see the foregoing verse) thine ear was not opened, i.e. thou didst not hear, to wit, from me; I did not reveal these things unto thee; for so this phrase of opening the ear is understood, 1 Samuel 9:15 2 Samuel 7:27. I knew that thou wouldest deal treacherously; I knew all these cautions were necessary to cure thine infidelity and apostacy. Wast called, to wit, justly and truly; or, thou wast indeed such a person; to be called put for to be, as we have oft noted.
