Oznayim la'Torah: When bringing something to Hakadosh-Baruch-Hu, one should do it generously. ¹

Pesachim, 75b: It implies red-hot coals - withut a flame - so that, upon entry into the Kodeh Kodshim, the coal will have lost some of its redness. ¹

Rashi: He took coals from the Mizbe'ach ha'Chitzon (which is only partly "Lifnei Hashem", as implied by the 'Hry' in "mi'Lifnei Hashm" - Yoma, 45a). ¹

Rashi: It means that he took the coals from the west side of the Mizbe'ach, which was the closest to the entrance to the Kodesh.

Sifra: He took a fistfiul - irrespective of the size of his fist ¹ (in the way that one would normally take it - the arm above and the fingers below - Yoma, 47b).

Sifra: "Ketores" teaches us .that - like the aily Ketores, it must come from public fnds, and "Samim", that it must include all eleven spices of the daily Ketores.

Rashi: This teaches us that the Ketores on Yom Kipur was grounded particularly fine (Dakah min ha'Dakah). ¹

Seforno: After Shechting his Chatas and reciting Viduy, he was free of sin, and therefore ready to receive the Shechinah, which was about to appear on the lid of the Aron, ¹ It was therefore appropriate to honor the Shechinah by entering Its presence with the Ketores. ²

Riva #1: Because before brining the Ketores, he would not be permitted to enter the Kodesh ha'Kodashim, since without the cloud of smoke he would die.

Riva #2 (citing R. Moshe of Pontaiza): He interrupts with Ketores, because when the cloud is there, it dispels the impression that he is benefitting from the radiance of the Shechinah.

Riva #3 (citing R. Yosef): Because once he begun sprinkling the bull's blood, he would not be able to interrupt until he finished with all the Haza'os. And if after pouring the Shirayim on the Mizbe'ach he would return inside for the Ketores, it would entail passing over Mitzvos.
