145. "And he shall go out to the altar that is before Hashem, and make atonement for it" (Vayikra 16:18). Rabbi Yehuda opened the discussion saying, "A psalm of Asaf. El, Elohim, Hashem, has spoken, and called the earth from the rising of the sun to the going down thereof" (Tehilim 50:1). We have learned that 1,550 tens of thousands of singers sing to the Holy One, blessed be He, with the first light of day, and 1,548 with the FIRST LIGHT OF moon, MEANING NIGHT. Another 1,590 tens of thousands SING PRAISE at the time of twilight.
145. וְיָצָא אֶל הַמִּזְבֵּחַ אֲשֶׁר לִפְנֵי יְיָ' וְכִפֶּר עָלָיו. ר' יְהוּדָה פָּתַח וְאָמַר, מִזְמוֹר לְאָסָף אֵל אֱלֹהִים יְיָ' דִּבֵּר וַיִּקְרָא אָרֶץ מִמִּזְרָח שֶׁמֶשׁ עַד מְבוֹאוֹ. תָּאנָא, אֲלַף וַחֲמֵשׁ מְאָה וְחַמְשִׁין רִבּוֹא מָארֵי שִׁירָתָא, מְזַמְּרִין לְקוּדְשָׁא בְּרִיךְ הוּא, כַּד נָהִיר יְמָמָא. וַאֲלַף וַחֲמֵשׁ מְאָה וְאַרְבְּעִין וּתְמַנְיָא בְּסִיהֲרָא. וַאֲלַף וַחֲמֵשׁ מְאָה וְתִשְׁעִין אֲלַף רִבּוֹא בְּהַהִיא שַׁעֲתָא דְּאִקְרֵי בֵּין הָעַרְבַּיִם.
150. We have learned that Rabbi Aba said: EVERYTHING THAT RABBI YEHUDA AND RABBI YOSI SAID is so. Above them are three Chiefs. HE EXPLAINS: At that time, when this morning is awakened and the praises are roused of all the 1,550 tens of thousands, there is appointed upon them one chief by the name of Heiman who counters HEIMAN of below, WHO IS MENTIONED IN TEHILIM. Under his offlicialdom, officers are appointed over them to set up the hymns. HEIMAN EQUALS THE LETTERS IN YEMIN (LIT. 'RIGHT'), AS HE DRAWS HIS STRENGTH FROM THE RIGHT.
150. תָּאנָא, א"ר אַבָּא, כֻּלְּהוּ הָכִי, וְעֵילָּא מִנְּהוֹן סַרְכִין תְּלָתָא. בְּהַהִיא שַׁעֲתָא דְּאִתְּעַר הַאי בֺּקֶר, וּמִתְעָרִין תּוּשְׁבְּחָן, כָּל אִינּוּן אֲלַף וַחֲמֵשׁ מְאָה וְחַמְשִׁין רִבּוֹא, אִתְמָנָא עָלַיְיהוּ חַד מְמָנָא, וְהֵימָן שְׁמֵיהּ לָקֳבְלֵיה דִּלְתַתָּא, וּתְחוֹת יְדֵיהּ סַרְכִין מְמָנָן עָלַיְיהוּ לְאַתְקְנָא שִׁירָתָא
