And Adam was not deceived — The serpent deceived Eve: Eve did not deceive Adam, but persuaded him. "Thou hast hearkened unto the voice of thy wife," Genesis 3:17. The preceding verse showed why a woman should not "usurp authority over the man." this shows why she ought not "to teach." She is more easily deceived, and more easily deceives. The woman being deceived transgressed — "The serpent deceived" her, Genesis 3:13, and she transgressed.
