וַיִּֽמְעֲל֔וּ בֵּאלֹהֵ֖י אֲבוֹתֵיהֶ֑ם וַיִּזְנ֗וּ אַחֲרֵי֙ אֱלֹהֵ֣י עַמֵּי־הָאָ֔רֶץ אֲשֶׁר־הִשְׁמִ֥יד אֱלֹהִ֖ים מִפְּנֵיהֶֽם׃
E furono infedeli al Dio dei loro padri, e si prostituirono dietro agli dèi dei popoli del paese, che Dio aveva sterminato davanti a loro.
Rashi
כי תמעל מעל — The term מעל everywhere in Scripture denotes “changing”. Similarly it stales, (I Chronicles 5:25) “And they committed a מעל against the God of their fathers; for they went a whoring after the gods of the people of the land” (i. e. they exchanged Him for their gods). And similarly it states of the faithless wife, (Numbers 5:12) “[If any man’s wife go aside] and commit a מעל in respect to him” (i. e. she changes her relationship to him for one to another man) (Sifra, Vayikra Dibbura d'Chovah, Section 11 1; Meilah 18a).
