אֶת־יְהוָ֖ה הָי֣וּ יְרֵאִ֑ים וְאֶת־אֱלֹֽהֵיהֶם֙ הָי֣וּ עֹֽבְדִ֔ים כְּמִשְׁפַּט֙ הַגּוֹיִ֔ם אֲשֶׁר־הִגְל֥וּ אֹתָ֖ם מִשָּֽׁם׃
ה׳ פֿלעגן זײ פֿאָרכטן, אָבער זײערע געטער פֿלעגן זײ דינען, אַזױ װי דער שטײגער פֿון די פֿעלקער װאָס מע האָט זײ פֿון דאָרטן אַװעקגעפֿירט.
Rashi
As was the custom of the nations from which they had been exiled. Those deities that are worshiped by the nations whom Sancheiriv and his armies had exiled (these) from there, they would worship here.36Alternatively, כמשפט הגוים refers to some of the Bnei Yisroel who also worshiped idols while worshiping God.—Radak
