Talmud for Ezekiel 9:2

וְהִנֵּ֣ה שִׁשָּׁ֣ה אֲנָשִׁ֡ים בָּאִ֣ים ׀ מִדֶּרֶךְ־שַׁ֨עַר הָעֶלְי֜וֹן אֲשֶׁ֣ר ׀ מָפְנֶ֣ה צָפ֗וֹנָה וְאִ֨ישׁ כְּלִ֤י מַפָּצוֹ֙ בְּיָד֔וֹ וְאִישׁ־אֶחָ֤ד בְּתוֹכָם֙ לָבֻ֣שׁ בַּדִּ֔ים וְקֶ֥סֶת הַסֹּפֵ֖ר בְּמָתְנָ֑יו וַיָּבֹ֙אוּ֙ וַיַּ֣עַמְד֔וּ אֵ֖צֶל מִזְבַּ֥ח הַנְּחֹֽשֶׁת׃

And, behold, six men came from the way of the upper gate, which lieth toward the north, every man with his weapon of destruction in his hand; and one man in the midst of them clothed in linen, with a writer’s inkhorn on his side. And they went in, and stood beside the brazen altar.
