Ezekiel 37:10 Kabbalah

וְהִנַּבֵּ֖אתִי כַּאֲשֶׁ֣ר צִוָּ֑נִי וַתָּבוֹא֩ בָהֶ֨ם הָר֜וּחַ וַיִּֽחְי֗וּ וַיַּֽעַמְדוּ֙ עַל־רַגְלֵיהֶ֔ם חַ֖יִל גָּד֥וֹל מְאֹד־מְאֹֽד׃ (ס)

So I prophesied as He commanded me, and the breath came into them, and they lived, and stood up upon their feet, an exceeding great host.
