שמות לט,לב : וַתֵכֶל כָּל־עֲבֹדַת מִשְכַן
The Baal HaTurim notes that the above phrase has the Gematria of 1392 which is equal to that phrase בעשרים וחמשה בכסלו נגמר (on the 25th of Kislev it was finished).
This refers to the Medrash that states that the work of making the components of the Mishkan was completed on the 25th of Kislev. However, HaShem delayed its inauguration until Nissan. Since this day was deprived of the inauguration, HaShem repaid that day in the time of the miracle of Chanukah when they rededicated the Bais haMikdash on that day.
Observe at Its Designated Times
שמות מ ,כג : כַאֲשֶר צִוָּה ה' אֶת־מֹשֶה
The Torah writes this with regard to each and every item that Betzalel manufactured that he did as was commanded by HaShem to Moshe.
The Baal haTurim comments that it is a reward for Moshe's having said "blot me out from Your Seifer ... (in defense of K'lal Yisrael)." Now the Torah makes a point of repeating his name over and over again. In fact, the Torah mentions this phrase eighteen times, and it is against this that Chazal instituted eighteen Berachos in the Amidah.
Further, there are 113 words in the repeated occurrence of the similar phrases (as was HaShem commanded Moshe); so too there are 113 words in the conclusion of the blessings of the Amidah.
In the same vein, the word "Leiv" (heart) appears a hundred and thirteen times in the Torah. This is equivalent, says the Baal haTurim, to the concluding words of all the Berachos in the Amidah ('Baruch Atah HaShem, Magen Avrohom'; 'Baruch Atah HaShem, Mechayeh ha'Meisim' ... ) - because the main concept in the Amidah is the concentration of one’s heart.
