וְנָטִ֤יתִי אֶת־יָדִי֙ עֲלֵיהֶ֔ם וְנָתַתִּ֨י אֶת־הָאָ֜רֶץ שְׁמָמָ֤ה וּמְשַׁמָּה֙ מִמִּדְבַּ֣ר דִּבְלָ֔תָה בְּכֹ֖ל מוֹשְׁבֽוֹתֵיהֶ֑ם וְיָדְע֖וּ כִּֽי־אֲנִ֥י יְהוָֽה׃ (פ)
And I will stretch out My hand upon them, and make the land desolate and waste, more than the wilderness of Diblah, throughout all their habitations; and they shall know that I am the LORD.’
Rashi on Ezekiel
and an astonishment Heb. ומשמה, a wonder, i.e., that all who see it will wonder about it.
