Shemot (Exodus) Chapter 12

25And it shall come to pass when you enter the land that the Lord will give you, as He spoke, that you shall observe this service.   כהוְהָיָ֞ה כִּֽי־תָבֹ֣אוּ אֶל־הָאָ֗רֶץ אֲשֶׁ֨ר יִתֵּ֧ן יְהֹוָ֛ה לָכֶ֖ם כַּֽאֲשֶׁ֣ר דִּבֵּ֑ר וּשְׁמַרְתֶּ֖ם אֶת־הָֽעֲבֹדָ֥ה הַזֹּֽאת:
And it shall come to pass when you enter Scripture makes this commandment contingent upon their entry into the land, but in the desert, they were obligated only to bring one Passover sacrifice, the one they performed in the second year, [which they did] by divine mandate. — [from Mechilta]   וְהָיָה כִּֽי־תָבֹאוּ אֶל־הָאָרֶץ  תָּלָה הַכָּתוּב עֲבוֹדָה זוֹ בְּבִיאָתָם לָאָרֶץ, וְלֹא נִתְחַיְּבוּ בַמִּדְבָּר אֶלָּא פֶּסַח אֶחָד שֶׁעָשׂוּ בַשָּׁנָה הַשֵּׁנִית עַל פִּי הַדִּבּוּר:
as He spoke Now where did He speak? “And I will bring you to the land, etc.” (Exod. 6:8). — [from Mechilta]   כַּֽאֲשֶׁר דִּבֵּר  וְהֵיכָן דִּבֵּר? "וְהֵבֵאתִי אֶתְכֶם אֶל הָאָרֶץ וְגוֹ'" (שמות ו'):
26And it will come to pass if your children say to you, What is this service to you?   כווְהָיָ֕ה כִּי־יֹֽאמְר֥וּ אֲלֵיכֶ֖ם בְּנֵיכֶ֑ם מָ֛ה הָֽעֲבֹדָ֥ה הַזֹּ֖את לָכֶֽם:
27you shall say, It is a Passover sacrifice to the Lord, for He passed over the houses of the children of Israel in Egypt when He smote the Egyptians, and He saved our houses. And the people kneeled and prostrated themselves.   כזוַֽאֲמַרְתֶּ֡ם זֶֽבַח־פֶּ֨סַח ה֜וּא לַֽיהֹוָ֗ה אֲשֶׁ֣ר פָּ֠סַ֠ח עַל־בָּתֵּ֤י בְנֵֽי־יִשְׂרָאֵל֙ בְּמִצְרַ֔יִם בְּנָגְפּ֥וֹ אֶת־מִצְרַ֖יִם וְאֶת־בָּתֵּ֣ינוּ הִצִּ֑יל וַיִּקֹּ֥ד הָעָ֖ם וַיִּשְׁתַּֽחֲוֽוּ:
And the people kneeled and prostrated themselves [in thanksgiving] for the tidings of the redemption, the entry into the land [of Israel], and the tidings of the children that they would have. — [from Mechilta]   וַיִּקֹּד הָעָם  עַל בְּשׂוֹרַת הַגְּאֻלָּה וּבִיאַת הָאָרֶץ וּבְשׂוֹרַת הַבָּנִים שֶׁיִּהְיוּ לָהֶם:
28So the children of Israel went and did; as the Lord commanded Moses and Aaron, so they did.   כחוַיֵּֽלְכ֥וּ וַיַּֽעֲשׂ֖וּ בְּנֵ֣י יִשְׂרָאֵ֑ל כַּֽאֲשֶׁ֨ר צִוָּ֧ה יְהֹוָ֛ה אֶת־משֶׁ֥ה וְאַֽהֲרֹ֖ן כֵּ֥ן עָשֽׂוּ:
So the children of Israel went and did Now did they already do [it]? Wasn’t this said to them on Rosh Chodesh? But since they accepted upon themselves [to do it], Scripture credits them for it as if they had [already] done [it]. — [from Mechilta]   וַיֵּֽלְכוּ וַיַּֽעֲשׂוּ בְּנֵי יִשְׂרָאֵל  וְכִי כְּבָר עָשׂוּ, וַהֲלֹא מֵרֹאשׁ חֹדֶשׁ נֶאֱמַר לָהֶם? אֶלָּא מִכֵּיוָן שֶׁקִּבְּלוּ עֲלֵיהֶם מַעֲלֶה עֲלֵיהֶם הַכָּתוּב כְּאִלּוּ עָשׂוּ (מכילתא):
went and did Scripture counts also the going, to give reward for the going and reward for the deed. — [from Mechilta]   וַיֵּֽלְכוּ וַיַּֽעֲשׂוּ  אַף הַהֲלִיכָה מָנָה הַכָּתוּב, לִתֵּן שָׂכָר לַהֲלִיכָה וְשָׂכָר לַעֲשִׂיָּה (שם):
as the Lord commanded Moses and Aaron [This comes] to tell Israel’s praise, that they did not omit anything of all the commandments of Moses and Aaron. And what is the meaning of “so they did?” Moses and Aaron also did so. — [from Mechilta]   כַּֽאֲשֶׁר צִוָּה ה' אֶת־משֶׁה וְאַֽהֲרֹן  לְהַגִּיד שִׁבְחָן שֶׁל יִשְׂרָאֵל שֶׁלֹּא הִפִּילוּ דָּבָר מִכָּל מִצְווֹת מֹשֶׁה וְאַהֲרֹן, וּמַהוּ כן עשו? אַף מֹשֶׁה וְאַהֲרֹן כֵּן עָשׂוּ (שם):
