Leviticus Chapter 23

1And the Lord spoke to Moses, saying,   אוַיְדַבֵּ֥ר יְהֹוָ֖ה אֶל־משֶׁ֥ה לֵּאמֹֽר:
2Speak to the children of Israel and say to them: The Lord's appointed [holy days] that you shall designate as holy occasions. These are My appointed [holy days]:   בדַּבֵּ֞ר אֶל־בְּנֵ֤י יִשְׂרָאֵל֙ וְאָֽמַרְתָּ֣ אֲלֵהֶ֔ם מֽוֹעֲדֵ֣י יְהֹוָ֔ה אֲשֶׁר־תִּקְרְא֥וּ אֹתָ֖ם מִקְרָאֵ֣י קֹ֑דֶשׁ אֵ֥לֶּה הֵ֖ם מֽוֹעֲדָֽי:
Speak to the children of Israel…The Lord’s appointed [holy days]: Designate the [times] of the festivals so that [all of] Israel will become accustomed to them, [meaning] that they should proclaim leap years for [the Jews in] the Diaspora who had uprooted themselves from their place to ascend to [Jerusalem for] the festivals, but who had not yet arrived in Jerusalem. [The leap year would enable them to arrive in time. Consequently, in ensuing years, they would not lose hope of arriving on time and would be encouraged to make the pilgrimage.]- [Torath Kohanim 23:139; Levush Ha’orah. See also Mizrachi , Nachalath Ya’akov , Sefer Hazikkaron , Yosef Hallel , Chavel]   דבר אל בני ישראל וגו' מועדי ה': עשה מועדות שיהיו ישראל מלומדין בהם, שמעברים את השנה על גליות שנעקרו ממקומם לעלות לרגל ועדיין לא הגיעו לירושלים:
3[For] six days, work may be performed, but on the seventh day, it is a complete rest day, a holy occasion; you shall not perform any work. It is a Sabbath to the Lord in all your dwelling places.   גשֵׁ֣שֶׁת יָמִים֘ תֵּֽעָשֶׂ֣ה מְלָאכָה֒ וּבַיּ֣וֹם הַשְּׁבִיעִ֗י שַׁבַּ֤ת שַׁבָּתוֹן֙ מִקְרָא־קֹ֔דֶשׁ כָּל־מְלָאכָ֖ה לֹ֣א תַֽעֲשׂ֑וּ שַׁבָּ֥ת הִוא֙ לַֽיהֹוָ֔ה בְּכֹ֖ל מֽוֹשְׁבֹֽתֵיכֶֽם:
[For] six days…: Why does the Sabbath [designated by God,] appear here amidst the festivals [designated by the Sanhedrin]? To teach you that whoever desecrates the festivals is considered [to have transgressed as severely] as if he had desecrated the Sabbath, and that whoever who fulfills the festivals is considered as if he has fulfilled the Sabbath, [and his reward is as great]. — [Be’er Basadeh ; Torath Kohanim 23:144]   ששת ימים: מה ענין שבת אצל מועדות, ללמדך שכל המחלל את המועדות מעלין עליו כאלו חלל את השבתות. וכל המקיים את המועדות, מעלין עליו כאלו קיים את השבתות:
