Contradiction with Genesis 3:16
This verse speaks of childbirth as a curse and source of pain, whereas Isaiah 26:17 uses childbirth as an analogy for something awaiting fulfillment.
Genesis 3:16: Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire [shall be] to thy husband, and he shall rule over thee. [to thy...: or, subject to thy husband]
Contradiction with John 16:21
Jesus highlights eventual joy following childbirth, contrasting Isaiah 26:17’s focus on pain and struggle.
John 16:21: A woman when she is in travail hath sorrow, because her hour is come: but as soon as she is delivered of the child, she remembereth no more the anguish, for joy that a man is born into the world.
