וָאֲטַמֵּ֤א אוֹתָם֙ בְּמַתְּנוֹתָ֔ם בְּהַעֲבִ֖יר כָּל־פֶּ֣טֶר רָ֑חַם לְמַ֣עַן אֲשִׁמֵּ֔ם לְמַ֙עַן֙ אֲשֶׁ֣ר יֵֽדְע֔וּ אֲשֶׁ֖ר אֲנִ֥י יְהוָֽה׃ (ס)
and I polluted them in their own gifts, in that they set apart all that openeth the womb, that I might destroy them, to the end that they might know that I am the LORD.
Rashi on Ezekiel
And I defiled them with their gifts Those gifts that I legislated for themto hallow for Me every firstborn—I delivered them into the hands of their temptation: to pass those firstborn to the Molech. Hence the statutes that are not good.
Rashi on Ezekiel
in order that I lay them desolate Heb. אֲשְּׁמֵם. I shall lay them desolate and destroy them. אֲשְּׁמֵם, is an expression of שְּׁמָמָה, desolation. Whoever explains it as an expression of אַשְּׁמָה, guilt, errs, because the ‘aleph’ is not part of the radical.
