וַיֹּ֨אמֶר מֹשֶׁ֜ה אֶל־יְהוָ֗ה רְ֠אֵה אַתָּ֞ה אֹמֵ֤ר אֵלַי֙ הַ֚עַל אֶת־הָעָ֣ם הַזֶּ֔ה וְאַתָּה֙ לֹ֣א הֽוֹדַעְתַּ֔נִי אֵ֥ת אֲשֶׁר־תִּשְׁלַ֖ח עִמִּ֑י וְאַתָּ֤ה אָמַ֙רְתָּ֙ יְדַעְתִּ֣יךָֽ בְשֵׁ֔ם וְגַם־מָצָ֥אתָ חֵ֖ן בְּעֵינָֽי׃
And Moses said unto the LORD: ‘See, Thou sayest unto me: Bring up this people; and Thou hast not let me know whom Thou wilt send with me. Yet Thou hast said: I know thee by name, and thou hast also found grace in My sight.

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].
