יחזקאל לח:א הלכה: Shulchan Arukh, Orach Chayim

3. We take out two Torah [scrolls]. From the first, we read "Look, you have been telling me..." [Exodus 33:12] and the maftir reads from the sacrifices corresponding to the possible day. The haftarah is from Ezekiel, "It will come to pass on the day that Gog comes..." [Ezekiel 38:18].
