Musar к Дварим 16:14

וְשָׂמַחְתָּ֖ בְּחַגֶּ֑ךָ אַתָּ֨ה וּבִנְךָ֤ וּבִתֶּ֙ךָ֙ וְעַבְדְּךָ֣ וַאֲמָתֶ֔ךָ וְהַלֵּוִ֗י וְהַגֵּ֛ר וְהַיָּת֥וֹם וְהָאַלְמָנָ֖ה אֲשֶׁ֥ר בִּשְׁעָרֶֽיךָ׃

И будешь радоваться празднику твоему, и ты, и сын твой, и дочь твоя, и раб твой, и служанка твоя, и левит, и незнакомец, и без отца, и вдова, которые в твоем ворота.

Shenei Luchot HaBerit

The word אורה is understood to refer to the spiritual illumination provided by Torah; the word שמחה to יום טוב, a holiday; the word ששון to circumcision, whereas the word ויקר is a reference to the phylacteries. The scriptural proof for the latter statement is derived from Deut. 28,10: "All mankind will see that the name of the Lord is on you and they will be in awe of you." Rabbi Eliezer the Great said that this is a reference to the phylacteries worn on the head.
