סימן צז סעיף ה
לְאַחַר הַלֵּל, אוֹמְרִים קַדִּישׁ שָׁלֵם, וּמוֹצִיאִין סֵפֶר תּוֹרָה וְקוֹרִין אַרְבָּעָה. הַכֹּהֵן קוֹרֵא שְׁלשָׁה פְּסוּקִים, שֶׁהֵם: וַידַבֵּר, צַו, וְאָמַרְתָּ. וְהַלֵּוִי חוֹזֵר וְקוֹרֵא וְאָמַרְתָּ, וְקוֹרֵא אֶת הַכֶּבֶשׂ אֶחָד, וַעֲשִׂירִית הָאֵיפָה. וְיִשְֹרָאֵל קוֹרֵא עוֹלַת תָּמִיד עַד וּבְרָאשֵׁי חָדְשֵׁיכֶם. וּרְבִיעִי קוֹרֵא וּבְרָאשֵׁי חָדְשֵׁיכֶם וגוֹ (תכ"ג).
After Hallel the whole Kaddish10On a day when there is a Mussaf service, the whole Kaddish is said after Hallel because Hallel marks the completion of the Shacharis (morning) prayer. Therefore on Chanukah, only the half-Kaddish is said after Hallel, as there is no Mussaf service. (Mishnah Berurah 423:1, Achronim) is recited, a Seifer Torah is taken out, and four (men) are called (to the Torah). The kohein reads three pesukim (verses), which are Vayedaber, Tzav, Veamarta. The Levi repeats the verse of V'amarta,11The reason for this is because at least three verses must be read, for each aliyah and also we must not stop less than three verses before the end of a parsha (sections). The parsha of the Tamid (the first parsha read on Rosh Chodesh) has only eight verses, and, therefore, in order to divide it into three aliyahs, some repetition is required. The parsha of Rosh Chodesh cannot be divided into two aliyahs because it has only five verses. Repetition cannot be used there because we must not start less than three verses in a parsha, nor stop less than three verses before the end of the parshah. and adds: Es hakkeves echad, veasiris haeifah. The Yisroel reads from olas tamid until uverashei chodsheychem. And the fourth person reads from uverashai chodsheychem.12Gaonim, Shulchan Aruch 423:2. But in Eretz Yisroel, the opinion of the Gra is widely accepted. He says the kohein reads the first three verses, the levi reads the next five, the third person repeats the last three verses read by the levi plus the two verses about Shabbos, and the fourth person reads the five verses about Rosh Chodesh.
