וְשָׂמַחְתָּ֖ בְּחַגֶּ֑ךָ אַתָּ֨ה וּבִנְךָ֤ וּבִתֶּ֙ךָ֙ וְעַבְדְּךָ֣ וַאֲמָתֶ֔ךָ וְהַלֵּוִ֗י וְהַגֵּ֛ר וְהַיָּת֥וֹם וְהָאַלְמָנָ֖ה אֲשֶׁ֥ר בִּשְׁעָרֶֽיךָ׃
And thou shalt rejoice in thy feast, thou, and thy son, and thy daughter, and thy man-servant, and thy maid-servant, and the Levite, and the stranger, and the fatherless, and the widow, that are within thy gates.
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.
