D.A.F.'s Moadim section

וּבִזְרֹעַ נְטוּיָה - זוֹ הַחֶרֶב, כְּמָה שֶּׁנֶּאֱמַר: וְחַרְבּוֹ שְׁלוּפָה בְּיָדוֹ, נְטוּיָה עַל יְרוּשָלָיִם.

"And with an outstretched arm" - This [refers to] the sword, as it is stated (I Chronicles 21:16); "And his sword was drawn in his hand, outstretched over Jerusalem."
