While I may have misunderstood his answer, I'd swear he said that the other part of the statement was that husbands needed to submit themselves to their wives.
He did say that Husbands should also submit which is close but not quite what the Bible says. It says something to the effect of Husbands should love their wives like Christ loved the church and gave himself up for her. I think Huckabee simply translated giving himself up for her as submitting - its not perfect theology but I wouldn’t nock him too much for it in an on the spot 90 second answer.
