Another note about not only prophecy, but Scripture in general:
Re:
I do not think Isaiah 4:1 has anything to do with polygyny whatsoever.
Why do people want to assume that if one meaning is True, another cannot be? Or that there cannot be other levels of meaning in addition as well?
One of the more ancient (and important) understandings of Scripture is that there are (at least) four levels of interpretation. (In the Hebrew,
paschat, remez, drash, sod.)
There is nothing wrong at all, of course, with the understanding that Scripture may have another meaning than the most obvious. But that does not mean that any of those levels of Truth should be discounted. Remember that in many cases (Hosea, certainly) the prophets note only WROTE and spoke of things to come, but literally lived out the physical example of the metaphor.
Seven, of course, is often called the number of
completion. Its use in Scripture speaks of something which is full, complete, and represents the whole. There is no reason at all not to think that it can be symbolic both of past and future, physical wives and churches (or spiritual wives), and perhaps other aspects of His plan as well.
But one thing is clear, and undeniable. It is a direct reference to Exodus 21:10. Those who want to understand the meaning on ANY level should recognize that the multiple wives of which the verse speaks KNOW and UNDERSTAND what the three duties of marriage spoken of are, and why. And, whether they are women, or churches, or
both and more, they understand more about the Word than EITHER most women, or most churches, today. That is why they know what they lack, and what they seek.
I do not for one minute suppose that there cannot be multiple fulfillment of His will in Scripture. But I do see clearly that this verse speaks to a need which is obvious and widespread today. In that sense it is a hopeful promise, and a comfort to those who hope and trust in Him.
Blessings,
Mark
