Deuteronomy 33:7 Kabbalah

וְזֹ֣את לִֽיהוּדָה֮ וַיֹּאמַר֒ שְׁמַ֤ע יְהוָה֙ ק֣וֹל יְהוּדָ֔ה וְאֶל־עַמּ֖וֹ תְּבִיאֶ֑נּוּ יָדָיו֙ רָ֣ב ל֔וֹ וְעֵ֥זֶר מִצָּרָ֖יו תִּהְיֶֽה׃ (ס)

And this for Judah, and he said: Hear, LORD, the voice of Judah, And bring him in unto his people; His hands shall contend for him, And Thou shalt be a help against his adversaries.
