Editing Rosh Chodesh (section)

==Origin==
The [[Book of Exodus]] establishes the new moon of [[Nisan]], which is the first month of [[Aviv]], as the beginning of the [[Hebrew calendar]]:
{{blockquote|And the {{lord}} spoke unto Moses and Aaron in the land of Egypt, saying: "This month shall mark for you the beginning of the months; it shall be the first of the months of the year for you."|Exodus 12:1-2<ref name="JPS">''JPS Hebrew-English Tanakh'', Second Edition. Philadelphia: The Jewish Publication Society, 2003.</ref>}}
In the [[Book of Numbers]], God speaks of the celebration of the new moon to Moses:
{{blockquote|And on your joyous occasions—your fixed festivals and new moon days—you shall sound the trumpets over your burnt offerings and your sacrifices of well-being.|Numbers 10:10<ref name="JPS"/>}}

In {{bibleverse||Psalm|81:4|HE}}, both new and full moon are mentioned as a time of recognition by the Hebrews:
{{blockquote|Blow the horn on the new moon, on the full moon for our feast day.<ref name="JPS"/><ref>Some [[English translations of the bible|translations]] refer to "the appointed time" rather than to the full moon, e.g. [[King James Version]] and [[Wycliffe Bible]]: the latter reads, "Blow ye with a trump in the new moon; in the noble day of your solemnity"</ref>}}

In the Bible, Rosh Chodesh is often referred to simply as "Chodesh", as the Hebrew word "chodesh" can mean both "month" and "new month".<ref>[https://mg.alhatorah.org/Dictionary/2320 Concordance - Dictionary: חֹדֶשׁ]</ref>
