Rosh Chodesh Nissan 5783

They are four New Years. On the first of Nisan is the New Year for kings; And for the Festivals. On the first of Elul is the New Year for animal tithes. Rabbi Elazar and Rabbi Shimon say: The New Year for animal tithes is on the first of Tishrei. On the first of Tishrei is the New Year for years, for Sabbatical Years and Jubilee Years, for planting, and for tithing vegetables. On the first of Shevat is the New Year for the tree; in accordance with the statement of Beit Shammai. But Beit Hillel say: The New Year for trees is on the fifteenth of Shevat.

החדש הזה — He showed him the moon in the first stage of its renewal, and He said to him, “The time when the moon renews itself thus, shall be unto you the beginning of the month”. (Mekhilta d'Rabbi Yishmael 12:2:2). But no Scriptural verse can lose its literal meaning, and He really spoke this in reference to the month Nisan: this month shall be the beginning in the order of counting the months, so that Iyar shall be called the second, Sivan the third.

THIS MONTH SHALL BE UNTO YOU THE BEGINNING OF MONTHS.
Now the purport of the expression, This month shall be unto you the beginning of months, is that Israel is to count this as the first of the months, and from it they are to count all months — second, third, etc., until a year of twelve months is completed — in order that there be through this enumeration a remembrance of the great miracle, [i.e., the exodus from Egypt, which occurred in the first month]. Whenever we will mention the months, the miracle will be remembered. It is for this reason that the months have no individual names in the Torah. Instead, Scripture says: In the third month; And it came to pass in the second year, in the second month … that the cloud was taken up from over the Tabernacle of the Testimony; And in the seventh month, on the first day of the month, etc., and so in all cases. Just as in counting the weekdays we always remember the Sabbath-day since the weekdays have no specific name of their own, but instead are called “one day in the Sabbath,” “the second day in the Sabbath,” as I will explain, so we remember the exodus from Egypt in our counting “the first month,” “the second month,” “the third month,” etc., to our redemption.
This order of the counting of the months is not in regard to the years, for the beginning of our years is from Tishri, [the seventh month], as it is written, And the feast of ingathering at the turn of the year, and it is further written, And the feast of ingathering, at the end of the year. If so, when we call the month of Nisan the first of the months and Tishri the seventh, the meaning thereof is “the first [month] to the redemption” and “the seventh month” thereto. This then is the intent of the expression, it shall be the first month to you, meaning that it is not the first in regard to the year but it is the first “to you,” i.e., that it be called “the first” for the purpose of remembering our redemption.
Our Rabbis have already mentioned this matter when saying, “The names of the months came up with us from Babylon,” since at first we had no names for the months. The reason for this [adoption of the names of the months when our ancestors returned from Babylon to build the Second Temple], was that at first their reckoning was a memorial to the exodus from Egypt, but when we came up from Babylon, and the words of Scripture were fulfilled — And it shall no more be said: As the Eternal liveth, that brought up the children of Israel out of the land of Egypt, but: As the Eternal liveth that brought up and that led the children of Israel from the land of the north — from then on we began to call the months by the names they were called in the land of Babylon. We are thus reminded that there we stayed [during our exile] and from there, blessed G-d brought us up [to our Land]. These names — Nisan, Iyar, and the others — are Persian names and are to be found only in the books of the prophets of the Babylonian era and in the Scroll of Esther. It is for this reason that Scripture says, In the first month, which is the month of Nisan, just as it says, they cast ‘pur,’ that is, the lot. To this day, people of Persia and Media use these names of the months — Nisan, Tishri, and the others — as we do. Thus through the names of the months we remember our second redemption even as we had done until then with regard to the first one.

It is taught in a baraita that the tanna’im disagreed about this point: Rabbi Eliezer says: In Tishrei the world was created; in Tishrei the Patriarchs were born; in Tishrei the Patriarchs died; on Passover Isaac was born; on Rosh HaShana Sarah, Rachel, and Hannah were remembered by God and conceived;

on Rosh HaShana Joseph came out from prison; on Rosh HaShana our forefathers’ slavery in Egypt ceased; in Nisan the Jewish people were redeemed from Egypt; and in Tishrei in the future the Jewish people will be redeemed in the final redemption with the coming of the Messiah.

Rabbi Yehoshua disagrees and says: In Nisan the world was created; in Nisan the Patriarchs were born; in Nisan the Patriarchs died; on Passover Isaac was born; on Rosh HaShana Sarah, Rachel, and Hannah were remembered by God and conceived sons; on Rosh HaShana Joseph came out from prison; on Rosh HaShana our forefathers’ slavery in Egypt ceased; in Nisan the Jewish people were redeemed from Egypt; and in Nisan in the future the Jewish people will be redeemed in the final redemption.
