Many times, one can find a hidden reference to future events in the Torah. Chanukah (spelled like that :), is a great example.
(לט) אַ֡ךְ בַּחֲמִשָּׁה֩ עָשָׂ֨ר י֜וֹם לַחֹ֣דֶשׁ הַשְּׁבִיעִ֗י בְּאָסְפְּכֶם֙ אֶת־תְּבוּאַ֣ת הָאָ֔רֶץ תָּחֹ֥גּוּ אֶת־חַג־יְהוָ֖ה שִׁבְעַ֣ת יָמִ֑ים בַּיּ֤וֹם הָֽרִאשׁוֹן֙ שַׁבָּת֔וֹן וּבַיּ֥וֹם הַשְּׁמִינִ֖י שַׁבָּתֽוֹן׃ (מ) וּלְקַחְתֶּ֨ם לָכֶ֜ם בַּיּ֣וֹם הָרִאשׁ֗וֹן פְּרִ֨י עֵ֤ץ הָדָר֙ כַּפֹּ֣ת תְּמָרִ֔ים וַעֲנַ֥ף עֵץ־עָבֹ֖ת וְעַרְבֵי־נָ֑חַל וּשְׂמַחְתֶּ֗ם לִפְנֵ֛י יְהוָ֥ה אֱלֹהֵיכֶ֖ם שִׁבְעַ֥ת יָמִֽים׃ (מא) וְחַגֹּתֶ֤ם אֹתוֹ֙ חַ֣ג לַֽיהוָ֔ה שִׁבְעַ֥ת יָמִ֖ים בַּשָּׁנָ֑ה חֻקַּ֤ת עוֹלָם֙ לְדֹרֹ֣תֵיכֶ֔ם בַּחֹ֥דֶשׁ הַשְּׁבִיעִ֖י תָּחֹ֥גּוּ אֹתֽוֹ׃ (מב) בַּסֻּכֹּ֥ת תֵּשְׁב֖וּ שִׁבְעַ֣ת יָמִ֑ים כָּל־הָֽאֶזְרָח֙ בְּיִשְׂרָאֵ֔ל יֵשְׁב֖וּ בַּסֻּכֹּֽת׃ (מג) לְמַעַן֮ יֵדְע֣וּ דֹרֹֽתֵיכֶם֒ כִּ֣י בַסֻּכּ֗וֹת הוֹשַׁ֙בְתִּי֙ אֶת־בְּנֵ֣י יִשְׂרָאֵ֔ל בְּהוֹצִיאִ֥י אוֹתָ֖ם מֵאֶ֣רֶץ מִצְרָ֑יִם אֲנִ֖י יְהוָ֥ה אֱלֹהֵיכֶֽם׃ (מד) וַיְדַבֵּ֣ר מֹשֶׁ֔ה אֶת־מֹעֲדֵ֖י יְהוָ֑ה אֶל־בְּנֵ֖י יִשְׂרָאֵֽל׃ (פ)
(39) Howbeit on the fifteenth day of the seventh month (i.e. Sukkot), when ye have gathered in the fruits of the land, ye shall keep the feast of the LORD seven days; on the first day shall be a solemn rest, and on the eighth day shall be a solemn rest. (40) And ye shall take you on the first day the fruit of goodly trees, branches of palm-trees, and boughs of thick trees, and willows of the brook, and ye shall rejoice before the LORD your God seven days. (41) And ye shall keep it a feast unto the LORD seven days in the year; it is a statute for ever in your generations; ye shall keep it in the seventh month. (42) Ye shall dwell in booths seven days; all that are home-born in Israel shall dwell in booths; (43) that your generations may know that I made the children of Israel to dwell in booths, when I brought them out of the land of Egypt: I am the LORD your God. (44) And Moses declared unto the children of Israel the appointed seasons of the LORD.
The very next verses, VaYikra 24:1-4, say:
(א) וַיְדַבֵּ֥ר יְהוָ֖ה אֶל־מֹשֶׁ֥ה לֵּאמֹֽר׃ (ב) צַ֞ו אֶת־בְּנֵ֣י יִשְׂרָאֵ֗ל וְיִקְח֨וּ אֵלֶ֜יךָ שֶׁ֣מֶן זַ֥יִת זָ֛ךְ כָּתִ֖ית לַמָּא֑וֹר לְהַעֲלֹ֥ת נֵ֖ר תָּמִֽיד׃ (ג) מִחוּץ֩ לְפָרֹ֨כֶת הָעֵדֻ֜ת בְּאֹ֣הֶל מוֹעֵ֗ד יַעֲרֹךְ֩ אֹת֨וֹ אַהֲרֹ֜ן מֵעֶ֧רֶב עַד־בֹּ֛קֶר לִפְנֵ֥י יְהוָ֖ה תָּמִ֑יד חֻקַּ֥ת עוֹלָ֖ם לְדֹרֹֽתֵיכֶֽם׃ (ד) עַ֚ל הַמְּנֹרָ֣ה הַטְּהֹרָ֔ה יַעֲרֹ֖ךְ אֶת־הַנֵּר֑וֹת לִפְנֵ֥י יְהוָ֖ה תָּמִֽיד׃ (פ)
(1) And the LORD spoke unto Moses, saying: (2) ’Command the children of Israel, that they bring unto thee pure olive oil beaten for the light, to cause a lamp to burn continually. (3) Without the veil of the testimony, in the tent of meeting, shall Aaron order it from evening to morning before the LORD continually; it shall be a statute for ever throughout your generations. (4) He shall order the lamps upon the pure candlestick (Menorah) before the LORD continually.
It's hard not to say that the direct mention of a Menorah just after Sukkot refers to Chanukah.
(טז) וַיַּ֨רְא יוֹסֵ֣ף אִתָּם֮ אֶת־בִּנְיָמִין֒ וַיֹּ֙אמֶר֙ לַֽאֲשֶׁ֣ר עַל־בֵּית֔וֹ הָבֵ֥א אֶת־הָאֲנָשִׁ֖ים הַבָּ֑יְתָה וּטְבֹ֤חַ טֶ֙בַח֙ וְהָכֵ֔ן כִּ֥י אִתִּ֛י יֹאכְל֥וּ הָאֲנָשִׁ֖ים בַּֽצָּהֳרָֽיִם׃
(16) And when Joseph saw Benjamin with them, he said to the steward of his house: ‘Bring the men into the house, and kill the beasts, and prepare the meat; for the men shall dine with me at noon.’
The five bolded letters are an anagram for Chanukah, and the phrase "וטבח טבח והכן", sans the 'ח והכן' which were used up in 'Chanukah', has a Gematria of 36- the total amount of candles used for the Mitzvah.
(כט) וַיִּשָּׂ֣א עֵינָ֗יו וַיַּ֞רְא אֶת־בִּנְיָמִ֣ין אָחִיו֮ בֶּן־אִמּוֹ֒ וַיֹּ֗אמֶר הֲזֶה֙ אֲחִיכֶ֣ם הַקָּטֹ֔ן אֲשֶׁ֥ר אֲמַרְתֶּ֖ם אֵלָ֑י וַיֹּאמַ֕ר אֱלֹהִ֥ים יָחְנְךָ֖ בְּנִֽי׃
If one replaces the 'י' with the other letters of G-d's name, 'ו' and 'ה', then it yields 'Chanukah'.
Finally, there are bits and pieces of hints elsewhere:
(א) וַיְהִ֡י בְּיוֹם֩ כַּלּ֨וֹת מֹשֶׁ֜ה לְהָקִ֣ים אֶת־הַמִּשְׁכָּ֗ן וַיִּמְשַׁ֨ח אֹת֜וֹ וַיְקַדֵּ֤שׁ אֹתוֹ֙ וְאֶת־כָּל־כֵּלָ֔יו וְאֶת־הַמִּזְבֵּ֖חַ וְאֶת־כָּל־כֵּלָ֑יו וַיִּמְשָׁחֵ֖ם וַיְקַדֵּ֥שׁ אֹתָֽם׃... (פט) וּבְבֹ֨א מֹשֶׁ֜ה אֶל־אֹ֣הֶל מוֹעֵד֮ לְדַבֵּ֣ר אִתּוֹ֒ וַיִּשְׁמַ֨ע אֶת־הַקּ֜וֹל מִדַּבֵּ֣ר אֵלָ֗יו מֵעַ֤ל הַכַּפֹּ֙רֶת֙ אֲשֶׁר֙ עַל־אֲרֹ֣ן הָעֵדֻ֔ת מִבֵּ֖ין שְׁנֵ֣י הַכְּרֻבִ֑ים וַיְדַבֵּ֖ר אֵלָֽיו׃ (פ)
(1) And it came to pass on the day that Moses had made an end of setting up the tabernacle, and had anointed it and sanctified it, and all the furniture thereof, and the altar and all the vessels thereof, and had anointed them and sanctified them... (89) And when Moses went into the tent of meeting that He might speak with him, then he heard the Voice speaking unto him from above the ark-cover that was upon the ark of the testimony, from between the two cherubim; and He spoke unto him.
The story of the dedication of the Mishkan, which is read on Chanukah, takes up 89 verses- the same number as the Gematria of 'Chanukah'.
(י) בְּעֶשְׂרִ֤ים וְאַרְבָּעָה֙ לַתְּשִׁיעִ֔י בִּשְׁנַ֥ת שְׁתַּ֖יִם לְדָרְיָ֑וֶשׁ הָיָה֙ דְּבַר־יְהוָ֔ה אֶל־חַגַּ֥י הַנָּבִ֖יא לֵאמֹֽר׃ (יא) כֹּ֥ה אָמַ֖ר יְהוָ֣ה צְבָא֑וֹת שְׁאַל־נָ֧א אֶת־הַכֹּהֲנִ֛ים תּוֹרָ֖ה לֵאמֹֽר׃
On the 24th of Kislev, Chaggai was sent to ask the Kohanim regarding Torah law. Chanukah, which starts on the night of the 25th of Kislev (and indeed, one should light candles at sunset or Bein Ha'Shemashot, in the transitional period between the 24th and 25th), is about how a group of Kohanim kept Torah law alive.
(א) הַ֥לְלוּ יָ֨הּ ׀ אַשְׁרֵי־אִ֭ישׁ יָרֵ֣א אֶת־יְהוָ֑ה בְּ֝מִצְוֺתָ֗יו חָפֵ֥ץ מְאֹֽד׃ (ב) גִּבּ֣וֹר בָּ֭אָרֶץ יִהְיֶ֣ה זַרְע֑וֹ דּ֭וֹר יְשָׁרִ֣ים יְבֹרָֽךְ׃ (ג) הוֹן־וָעֹ֥שֶׁר בְּבֵית֑וֹ וְ֝צִדְקָת֗וֹ עֹמֶ֥דֶת לָעַֽד׃ (ד) זָ֘רַ֤ח בַּחֹ֣שֶׁךְ א֭וֹר לַיְשָׁרִ֑ים חַנּ֖וּן וְרַח֣וּם וְצַדִּֽיק׃ (ה) טֽוֹב־אִ֭ישׁ חוֹנֵ֣ן וּמַלְוֶ֑ה יְכַלְכֵּ֖ל דְּבָרָ֣יו בְּמִשְׁפָּֽט׃ (ו) כִּֽי־לְעוֹלָ֥ם לֹא־יִמּ֑וֹט לְזֵ֥כֶר ע֝וֹלָ֗ם יִהְיֶ֥ה צַדִּֽיק׃ (ז) מִשְּׁמוּעָ֣ה רָ֭עָה לֹ֣א יִירָ֑א נָכ֥וֹן לִ֝בּ֗וֹ בָּטֻ֥חַ בַּיהוָֽה׃ (ח) סָמ֣וּךְ לִ֭בּוֹ לֹ֣א יִירָ֑א עַ֖ד אֲשֶׁר־יִרְאֶ֣ה בְצָרָֽיו׃ (ט) פִּזַּ֤ר ׀ נָ֘תַ֤ן לָאֶבְיוֹנִ֗ים צִ֭דְקָתוֹ עֹמֶ֣דֶת לָעַ֑ד קַ֝רְנ֗וֹ תָּר֥וּם בְּכָבֽוֹד׃ (י) רָ֘שָׁ֤ע יִרְאֶ֨ה ׀ וְכָעָ֗ס שִׁנָּ֣יו יַחֲרֹ֣ק וְנָמָ֑ס תַּאֲוַ֖ת רְשָׁעִ֣ים תֹּאבֵֽד׃
(1) Hallelujah. Happy is the man that feareth the LORD, That delighteth greatly in His commandments. (2) His seed shall be mighty upon earth; The generation of the upright shall be blessed. (3) Wealth and riches are in his house; And his merit endureth for ever. (4) Unto the upright He shineth as a light in the darkness, Gracious, and full of compassion, and righteous. (5) Well is it with the man that dealeth graciously and lendeth, That ordereth his affairs rightfully. (6) For he shall never be moved; The righteous shall be had in everlasting remembrance. (7) He shall not be afraid of evil tidings; His heart is stedfast, trusting in the LORD. (8) His heart is established, he shall not be afraid, Until he gaze upon his adversaries. (9) He hath scattered abroad, he hath given to the needy; His righteousness endureth for ever; His horn shall be exalted in honour. (10) The wicked shall see it, and be vexed; he shall gnash with his teeth, and melt away; the desire of the wicked shall perish.
The Gematria of 'מכבים', 'Maccabees', is 112, and Tehillim 112 talks about four things: a) The G-d fearing (Matityahu) having mighty children (the Maccabees), b) the kindling of light (the Menorah) amidst the darkness, c) the everlasting remembrance of the righteous (Maccabees- we celebrate Chanukah, until this very day), and d) the frustration of the wicked (Seleucid Empire) when their desire (Judean assimilation) falls out of their grasp.
