Prophecy is a communication direct from G-d through a prophet to the people of his or her generation. The message may or may not contain visions of future events. The message may have importance to future generations (us), and those were written down for posterity in the Torah (the prophecies of Moses) and Nevi'im (Prophets) in the T'nach.
Prophecy is always based on the plain meaning of the text -- not on hints or "shadows." Consider the famous chapter of Y'shayahu / Isaiah 7. it does not speak about virgins giving birth, and the woman (and her child) are incidental to the actual prohecy which was for the then living king, אָחָז / Ahaz.
Y'shayahu / Isaiah 7 begins "And it came to pass in the days of Ahaz son of Jotham son of Uzziah, king of Judah, that Rezin, king of Aram, and Pekah son of Remaliah, king of Israel, marched on Jerusalem to wage war against it, and he could not wage war against it."
G-d tells Isaiah (prophecy! direct communication of G-d to Isaiah) to go to King Ahaz and tell him: "Feel secure and calm yourself, do not fear, and let your heart not be faint because of these two smoking stubs of firebrands, because of the raging anger of Rezin and Aram and the son of Remaliah." (verse 4).
So the prophecy is for King Ahaz, the prophet is Isaiah. The message is "don't be afraid of the two kings (Rezin and Pekah)."
Prophecy is never based on hints, or shadows or vague possibilities. Judaism is replete with stories and "tall tales" -- but those are not literal and are not meant to be taken literally. A principle of the Talmud that Rashi quotes several times states that אֵין מִקְרָא יוֹצֵא מִידֵי פְשׁוּטוֹ -- in English this would be "A verse cannot depart from its plain meaning." (Treatise Shabbat 63a, Treatise Y'vamot 11b, 24a; quoted by Rashi at B'réshıt / Genesis 15:10, 37:19, and Sh'mot / Exodus 12:2).
Likewise the concept of "dual fulfillment" is totally non-biblical.
Missionaries often reference midrashim (stories meant to make a moral point) as if they were prophetic -- either from ignorance or malice.
Thus a "secondary message" that is not clear (requires drash, aka "types and shadows" let alone "dual prophecy") violates the very concept of prophecy itself. Even a "first message" which came directly from G-d (required to be prophecy) that was unclear or required interpreting hints (remez) or inferring something that isn't clearly there (drash) doesn't fit the definition of prophecy.
For those reading this who do not know the terms p'shat, drash and sod, these terms relate to the various levels the Jewish bible is read, PaRDeS:
* P'shat (פְּשָׁט) - the "plain" ("simple") meaning of a passage (prophecy is always based on 'pshat)
* Remez (רֶמֶז) - "hints" implied in the text but not explicit
* Drash (דְּרַשׁ) - which is a deeper or even midrashic meaning -- often inferred from other scripture
* Sod (סוֹד) - "secret" ("mystery") meanings
On top of all that prophecy is never hidden.
The Jewish bible itself never once gives an example of a prophecy being "dual" or being "hidden."
Thus the Christian concept of changing the meanings long after the fact are simply not supported in the Jewish bible.
The real meaning of any biblical passage is the p'shat (plain meaning). Everything else is a kind of midrash, -- a story which is not literal, but is meant to teach some supplementary message.
The Rambam wrote: "I maintain that it is not proper for a person to stroll in the Pardes unless he has filled his belly with bread and meat. "Bread and meat" refer to the knowledge of what is permitted and what is forbidden, and similar matters concerning other mitzvot. Even though the Sages referred to these as "a small matter" - for our Sages said: "'A great matter,’ this refers to Ma'aseh Merkavah ("Maaseh Merkavah" and "Maaseh Bereishit," are the mystical study of the Creator and His Creation). `A small matter,’ this refers to the debates of Abbaye and Ravva" - nevertheless, it is fitting for them to be given precedence, because they settle a person's mind." Yesodei haTorah, chapter 4.
Missionaries will dabble quoting sages speaking of drash or remez -- as if they are literal. They are doing so out of ignorance -- and as the Rambam continued to state "strolling in the PaRDeS (orchard) is restricted to accomplished Torah scholars who are already well founded in the literal understanding of the Torah (p'shat)...He stated:
"The Sages of the early generations commanded that these matters should not be expounded upon in public." Yesodei haTorah, chapter 4.
The Orthodox Union puts it well:
"Some authorities maintain that there should be a general limit on the study of kabbalah and other esoteric subjects. Rabbi Shlomo Luria, the Maharshal (d. 1573) complains (Shu”t 98 ) about ignoramuses learning kabbalah.
"The Rema equates the substance of philosophy and kabbalah and penned a lengthy essay (Torat Ha’olah, part 3, ch. 4) and a long response (Shu”t 7) on the topic of studying them. He displays intimate familiarity with kabbalah, and explains that he personally only studies such matters on Shabbat, yom tov and Chol HaMoed, and uses the rest of his time to study Mishnah, Talmud, halachah and the relevant commentaries. (Similarly, the Sanzer Rav, Rabbi Chaim Halberstam, states that the essence of life is to study the main parts of Torah all day, and that he involves himself with kabbalah when other people are in their beds and he is fighting off sleep [Divrei Chaim 2, YD 47]).
"The Maharshal derives his knowledge of philosophy only from Jewish sources such as Rambam. The Rema bemoans the lack of true kabbalists and that instead “every bore who knows not his right from his left and cannot learn parashah with Rashi, jumps to learn kabbalah."
Prophecy is NEVER based on drash, still less from rĕmĕz or sod. Prophecy is only based on a text’s p'shat (actual meaning)—never on d'rash (sermons derived from, or based on, it). The Talmud tells us: "A verse cannot depart from its plain meaning." Shabbat 63a, Y'vamot 11b, and Y'vamot 24a. Rashi, the 11th century Torah commentator, quotes this at B'reshit / Genesis 15:10, 37:19 and Sh'mot / Exodus 12:2).
