Question:
Which portion of the Torah is read on Rosh Chodesh?
Response:
On Rosh Chodesh, the "head" of the new month, we read four aliyahs from Numbers 28. The requirements for any aliyah is a minimum of three verses. In Numbers 28, along with the daily and weekly Temple sacrifices, we read of the special offerings brought in honor of Rosh Chodesh. Here is the aliyah breakdown:
First aliyah (Kohen): verses 1-3
Second aliyah (Levi): verses 3-5 (No, that was not a mistake, we do read verse 3 twice.)
Third aliyah: verses 6-10
Fourth aliyah: verses 11-151
Please let me know if this helps.
Yours truly,
Rabbi Menachem Posner
