The first verse of Ki Tavo's Haftarah is brought by the Ramchal in Maamar haGeulah as being a verse in the Tanach which mentions both the Pekidah and the Zechirah.
The first word, קומי, is directed at the Shechinah, which must arise from the dust of exile at the time of Pekidah. Why? Because soon the Shechinah will receive its light directly from Z"A, when the Nesirah is complete, and the Zechirah arrives.
But in the process, the darkness first will cover the world. The verse says the darkness will cover the nations. The implication being that Zion is our refuge.
