The Tefillin include the Shema Israel prayer with two large letters, ע and ד.
” Hear, O Israel: YHVH our God, YHVH is one.”
We have studied many times before, about the power of the Shema Israel prayer. The Zohar teaches us that the two large letters עד spell ‘witness’. The large ע, numerically 70 connects us to the 72 names that has 70 unique names and two doubles that defined as ‘witnesses’.
The names draw the light of Chokmah from the upper Garden of Eden to Zeir Anpin and Malchut.
YHVH is our witness and that means that he is always by our side, keeping account on all of our actions. This ‘witnessing’ process has great joy in it for those who connect and entitled for it.
1 Samuel 12: 5
” וַיֹּאמֶר אֲלֵיהֶם עֵד יְהוָה בָּכֶם, וְעֵד מְשִׁיחוֹ הַיּוֹם הַזֶּה–כִּי לֹא מְצָאתֶם בְּיָדִי, מְאוּמָה; וַיֹּאמֶר, עֵד.”
“And he said to them, “YHVH is witness (עֵד) against you, and his anointed (Mashiach) is witness (עֵד) this day, that you have not found anything in my hand.” And they said, “He is witness (עֵד).””
