The IDF has launched a major Gaza operation named “Amud Annan (Pillar/Column of Defense)” with the goal of taking “out a large piece of the (Hamas) command structure without toppling the regime,” a knowledgeable source in Jerusalem told The Algemeiner.
Yeranen Yaakov discusses the derivation of the name of the latest IDF operation in Gaza, "Amud He'anan" which translates to "Pillar of cloud." (Pillar of defense)
He references the verse in Exodus 14: 19.
I discovered a few more references here including the one below.
But You,with Your abundant mercies, did not forsake them in the desert; the pillar of cloud did not turn away from them by day to lead them on the way, neither did the pillar of fire at night to illuminate for them the way in which they should go.
יט. וְאַתָּה בְּרַחֲמֶיךָ הָרַבִּים לֹא עֲזַבְתָּם בַּמִּדְבָּר אֶת עַמּוּד הֶעָנָן לֹא סָר מֵעֲלֵיהֶם בְּיוֹמָם לְהַנְחֹתָם בְּהַדֶּרֶךְ וְאֶת עַמּוּד הָאֵשׁ בְּלַיְלָה לְהָאִיר לָהֶם וְאֶת הַדֶּרֶךְ אֲשֶׁר יֵלְכוּ בָהּ:
May Hashem illuminate for us the way to go and protect us. I'm off to say some Pirkei Tehillim.
