אָ֤ב וָאֵם֙ הֵקַ֣לּוּ בָ֔ךְ לַגֵּ֛ר עָשׂ֥וּ בַעֹ֖שֶׁק בְּתוֹכֵ֑ךְ יָת֥וֹם וְאַלְמָנָ֖ה ה֥וֹנוּ בָֽךְ׃
Chez toi, l’on a outragé père et mère; chez toi on a pressuré durement l’étranger, spolié l’orphelin et la veuve.
Tze'enah Ure'enah
“Fathers and mothers have been humiliated” [22:7]. They did not honor father and mother and these are the greatest sins. Even if the Torah did not command respect for father and mother, it would have been correct to respect father and mother. The stranger, the orphan and the widow, they have defrauded.
Rashi
Father and mother are held light in you All the abominations in the section of (Lev. 19, 20) “You shall be holy,” about which they were warned, are enumerated here.
