Pesach Sheini in the Wilderness
(5) and they offered the passover sacrifice in the first month, on the fourteenth day of the month, at twilight, in the wilderness of Sinai. Just as the Eternal One had commanded Moses, so the Israelites did. (6) But there were some men who were unclean by reason of a corpse and could not offer the passover sacrifice on that day. Appearing that same day before Moses and Aaron, (7) those men said to them, “Unclean though we are by reason of a corpse, why must we be debarred from presenting the Eternal’s offering at its set time with the rest of the Israelites?” (8) Moses said to them, “Stand by, and let me hear what instructions the Eternal gives about you.” (9) And the Eternal One spoke to Moses, saying: (10) Speak to the Israelite people, saying: When any of you or of your posterity who are defiled by a corpse or are on a long journey would offer a passover sacrifice to the Eternal, (11) they shall offer it in the second month, on the fourteenth day of the month, at twilight. They shall eat it with unleavened bread and bitter herbs, (12) and they shall not leave any of it over until morning. They shall not break a bone of it. They shall offer it in strict accord with the law of the passover sacrifice.
Pesach Sheini for the Rabbis
(ז) גֵּר שֶׁנִּתְגַּיֵּר בֵּין פֶּסַח רִאשׁוֹן לְפֶסַח שֵׁנִי. וְכֵן קָטָן שֶׁהִגְדִּיל בֵּין שְׁנֵי פְּסָחִים. חַיָּבִין לַעֲשׂוֹת פֶּסַח שֵׁנִי. וְאִם שָׁחֲטוּ עָלָיו בָּרִאשׁוֹן פָּטוּר:
(ח) נָשִׁים שֶׁנִּדְּחוּ לַשֵּׁנִי. בֵּין מִפְּנֵי הָאֹנֶס וְהַשְּׁגָגָה. בֵּין מִפְּנֵי הַטֻּמְאָה וְדֶרֶךְ רְחוֹקָה. הֲרֵי פֶּסַח שֵׁנִי לָהֶם רְשׁוּת. רָצוּ שׁוֹחֲטִין רָצוּ אֵין שׁוֹחֲטִין. לְפִיכָךְ אֵין שׁוֹחֲטִין עֲלֵיהֶן בִּפְנֵי עַצְמָן בְּשַׁבָּת בְּפֶסַח שֵׁנִי. אֲבָל אִם הָיְתָה הָאִשָּׁה אַחַת מִבְּנֵי חֲבוּרָה מֻתָּר. וְאֵי זוֹ הִיא דֶּרֶךְ רְחוֹקָה. חֲמִשָּׁה עָשָׂר מִיל חוּץ לְחוֹמַת יְרוּשָׁלַיִם:
A convert who converts between the first Pesach and the second Pesach and similarly, a child who comes of age between these two holidays are obligated to offer the second Paschal sacrifice. If one slaughtered the first Paschal sacrifice for the sake of the minor, the minor is exempt from bringing the second sacrifice.
When the obligation of women is postponed until the second Pesach, whether because of forces beyond their control, inadvertent omission, impurity, or because they were "on a distant way," offering the second Paschal sacrifice is optional for them. If they desire, they may have the offering slaughtered; if they do not desire, they don't. Therefore one should not slaughter a Paschal sacrifice only for women when the second Pesach falls on the Sabbath. If, however, a woman is part of the company offering a second Paschal sacrifice, it is permitted.
What is meant by the term "on a distant way" which exempts a person from bringing a Paschal sacrifice? Fifteen mil outside the walls of Jerusalem.
Sukkot Sheini for the Maccabees
1 Maccabees 4:47-59
47 Then they took whole stones according to the law, and built a new altar according to the former;
48 And made up the sanctuary, and the things that were within the temple, and hallowed the courts.
49 They made also new holy vessels, and into the temple they brought the candlestick, and the altar of burnt offerings, and of incense, and the table.
50 And upon the altar they burned incense, and the lamps that were upon the candlestick they lighted, that they might give light in the temple.
51 Furthermore they set the loaves upon the table, and spread out the veils, and finished all the works which they had begun to make.
52 Now on the five and twentieth day of the ninth month, which is called the month Casleu, in the hundred forty and eighth year, they rose up betimes in the morning,
53 And offered sacrifice according to the law upon the new altar of burnt offerings, which they had made.
54 Look, at what time and what day the heathen had profaned it, even in that was it dedicated with songs, and citherns, and harps, and cymbals.
55 Then all the people fell upon their faces, worshipping and praising the God of heaven, who had given them good success.
56 And so they kept the dedication of the altar eight days and offered burnt offerings with gladness, and sacrificed the sacrifice of deliverance and praise.
57 They decked also the forefront of the temple with crowns of gold, and with shields; and the gates and the chambers they renewed, and hanged doors upon them.
58 Thus was there very great gladness among the people, for that the reproach of the heathen was put away.
59 Moreover Judas and his brethren with the whole congregation of Israel ordained, that the days of the dedication of the altar should be kept in their season from year to year by the space of eight days, from the five and twentieth day of the month Casleu, with mirth and gladness.
2 Maccabees 1:1-9
1 The brethren, the Jews that be at Jerusalem and in the land of Judea, wish unto the brethren, the Jews that are throughout Egypt health and peace:
2 God be gracious unto you, and remember God's covenant made with Abraham, Isaac, and Jacob, God's faithful servants;
3 And give you all an heart to serve the Eternal, and to do God's will, with a good courage and a willing mind;
4 And open your hearts in God's law and commandments, and send you peace,
5 And hear your prayers, and be at one with you, and never forsake you in time of trouble.
6 And now we be here praying for you.
7 What time as Demetrius reigned, in the hundred threescore and ninth year (of the Selucid era), we the Jews wrote unto you in the extremity of trouble that came upon us in those years, from the time that Jason and his company revolted from the holy land and kingdom,
8 And burned the porch, and shed innocent blood: then we prayed unto the Eternal One, and were heard; we offered also sacrifices and fine flour, and lighted the lamps, and set forth the loaves.
9 And now see that you keep the feast of tabernacles in the month Casleu.
2 Maccabees 10:1-8
1 Now Maccabeus and his company, the Eternal guiding them, recovered the temple and the city:
2 But the altars which the heathen had built in the open street, and also the chapels, they pulled down.
3 And having cleansed the temple they made another altar, and striking stones they took fire out of them, and offered a sacrifice after two years, and set forth incense, and lights, and shewbread.
4 When that was done, they fell flat down, and besought the Eternal that they might come no more into such troubles; but if they sinned any more against him, that he himself would chasten them with mercy, and that they might not be delivered unto the blasphemous and barbarous nations.
5 Now upon the same day that the strangers profaned the temple, on the very same day it was cleansed again, even the five and twentieth day of the same month, which is Casleu.
6 And they kept the eight days with gladness, as in the feast of the tabernacles, remembering that not long afore they had held the feast of the tabernacles, when as they wandered in the mountains and dens like beasts.
7 Therefore they bare branches, and fair boughs, and palms also, and sang psalms unto him that had given them good success in cleansing his place.
8 They ordained also by a common statute and decree, That every year those days should be kept of the whole nation of the Jews.
