For she did not know that I gave her the grain, the new wine, and the oil, And multiplied to her silver and gold, which they used for Baal.
"She did not know ..." There was no excuse for this intellectual blindness.  Israel, indeed the whole human race, had once known the true God  (Romans 1:21).  Prophet after prophet had pleaded with them in vain not to forget God, but to no avail.  The thought of this verse was featured by Jesus himself in his sentence of destruction upon the city of Jerusalem, when he exclaimed: "If thou hadst known in this thy day, even thou, the things which belong unto thy peace! but now are they hid from thine eyes" (Luke 19:42).  By that late date, when Jesus thus cried out against the city, it was apparent that the whore would never know (except for the righteous remnant).
