Jesus told the woman to go get her husband.Jesus seems to be saying she had a husband out there somewhere. He then told her she had had five husbands.
Jesus did not say she had been married and divorced 5 times, but that she had had 5 husbands.
Several ways to look at that, I suppose. She had been married and divorced 5 times. That seems unlikely to me, given the culture, and that isnt what Jesus said.
That she had been with 5 men who were the husbands of other women. Could be, i guess, but Jesus indicates the 5 men were each a husband to her, not to other women.
She had no husband and the man she was with was not her husband.
Seems to me Jesus is telling her she does have a husband. The first man she became one flesh with. She then had relations with 5 other men, becoming one flesh - husband and wife- and the last one that she was currently with was not her original husband. The original bond of marriage had been broken by her unfaithfulness.
Jesus is trying to get her to understand the true nature of the marriage relationship and her need to repent for her undaithfulness to her husband.
But Jesus said to her "Go, call your husband, and come here." [Jesus knew she had no husband but wanted her to say so.] The woman answered him, "I have no husband." Jesus said to her, "You are right in saying, 'I have no husband' [so the man she has now is not her husband even though she sleeps with him); for you have had five husbands, and the one you now have is not your husband. What you have said is true."
Jesus knew she wasn't married. She had been married 5 times before and for whatever reason, those marriages are no longer valid (because Jesus uses the past tense here). Now the man she had was not her husband so she was sleeping with him without him becoming her husband by nature of the sexual act. There is more to create a marriage than just a physical act.
