דברים ד, לד: אוֹ הֲנִסָה אֱלֹּ_ִים לָבוֹא לָקַחַת לוֹ גוֹי מִקֶרֶב גּוֹי בְמַסֹּת בְאֹּתֹּת וּבְמוֹפְתִים וּבְמִלְחָמָה וּבְיָד חֲזָקָה וּבִזְרוֹעַ נְטוּיָה וּבְמוֹרָאִים גְּדֹּלִים כְ כֹּל אֲשֶר-עָשָה לָכֶם ה' אֱלֹּ_ֵּיכֶם בְמִצְרַיִם לְעֵּינֶיךָ:
Baal HaTurim notes that every letter of the Alef-Beis is contained in this verse. There are many allusions connected to this. HaShem took the bnei Yisroel out of Egypt conditional to their accepting the Torah, which is written in the 22 letters of the Alef-Beis.
Further, this is quite a list of powerful activities that HaShem has done in Egypt to bring about the exodus. Seven aspects of strength are mentioned here to allude to the seven days (most of the plagues) that each plague lasted. This also alludes to the seven days of Pesach.
Baal haTurim also explains that HaShem really intended to give us the Torah (symbolized by the 'Alef-Beis') in Egypt. Then why didn't He?
Because the Midas haDin insisted that Yisrael must be given a trial period. And that explains why, he says, we find the word "haNisoh" in one other place in Tanach, where it means 'test'. The Pasuk in Iyov (4,2) writes "If He tests you ("haNisoh") with one thing you will become weary".
This hints at the claim of the Midas haDin, 'Test them before You teach them Your words' which we just referred to.
