And it came to pass on the day that Moshe ended the erection of the mishkan...
The Medrash says that the word כַּלּוֹת is written without a ו', as כַלַ ת with the meaning of becoming a bride. However, the Ohr Hachaim asks that he looked into the Sefer Torah and he found a ויו in this word.
The Ohr Hachaim writes that these types of divrei Torah should not be available for everyone, including those who would use them to fight against the Torah and Yiddishkeit. This would result in heresy and denigration of teachers and leaders. We need to accept that the letters and words of the Torah are quite precise. Not one letter or word is extra. All are hewn from a holy source and are wonderful to those who get to know them properly.
Some letters are expressed by mouth but not written into the word. For example, the וי"ו of יהשוע. In the written text, we find the word written out as יהשע. This shows us that the letters of the Torah serve more than merely to tell you how to read the words. Great secrets are revealed in the way words are written.
It is possible that the word is written in this way in order to place the name of Hashem with the name of the Tzadik. The שי"ן and the עי"ן have a numerical value of 370, and Kabbalah speaks of 370 lights. If a וי"ו would have been added, we would not have been able to realize this connection.
Those that truly understand the method of letters in the Torah will understand how things work, and they will appreciate that this possuk says כַלַ ת and not כַלוֹת. The letter וי"ו that we find there is only borrowed, it does not really belong there. Here, the Ohr Hachaim gives an esoteric explanation for this, based on a possuk in Yirmiyah (31:21) כִי בָרָא ה' חֲדָשָׁה בָאָרֶץ נְּקֵבָה תְּ סוֹבֵב גָבֶר. For Hashem has created a new thing in the earth, a woman shall encompass a man." The וי"ו represents the groom, which is surrounded by the word כַלַ ת, which is the bride. The bride surrounds the groom. Moshe was the groom, and Klal Yisroel was the bride.
This is the secret that only the Chachamim could reveal in this possuk, we would never deduce it on our own.
