Rosh Hashanah4: 6
אֵין פּוֹחֲתִין מֵעֲשָׂרָה מַלְכִיּוֹת, מֵעֲשָׂרָה זִכְרוֹנוֹת, מֵעֲשָׂרָה שׁוֹפָרוֹת. רַבִּי יוֹחָנָן בֶּן נוּרִי אוֹמֵר: אִם אָמַר שָׁלֹשׁ שָׁלֹשׁ מִכֻּלָּן, יָצָא. אֵין מַזְכִּירִין זִכְרוֹן מַלְכוּת וְשׁוֹפָר שֶׁל פֻּרְעָנוּת.  מַתְחִיל בַּתּוֹרָה וּמַשְׁלִים בַּנָּבִיא. רַבִּי יוֹסֵי אוֹמֵר: אִם הִשְׁלִים בַּתּוֹרָה, יָצָא.
They recite no fewer than ten Kingship [verses], than ten Remembrance [verses], than ten Shofar [verses]. R’ Yochanan ben Nuri says: If he recited three [verses] from each of them, he has discharged his obligation.  They should not recite [any verse of] Remembrance, Kingship, or Shofar which alludes to punishment.  He begins with [verses from] the Torah and concludes with [verses from] the Prophets. R’ Yose says: If he concluded with [verses from] the Torah, he has discharged his obligation.
