Exodus 34:17

פֶּן־תִּכְרֹת בְּרִית לְיוֹשֵׁב הָאָרֶץ וְזָנוּ אַחֲרֵי אֱלֹֽהֵיהֶם וְזָבְחוּ לֵאלֹהֵיהֶם וְקָרָא לְךָ וְאָכַלְתָּ מִזִּבְחֽוֹ

lest thou make a covenant with the inhabitants of the land, and they go astray after their gods, and do sacrifice unto their gods, and they call thee, and thou eat of their sacrifice;

וְלָקַחְתָּ מִבְּנֹתָיו לְבָנֶיךָ וְזָנוּ בְנֹתָיו אַחֲרֵי אֱלֹהֵיהֶן וְהִזְנוּ אֶת־בָּנֶיךָ אַחֲרֵי אֱלֹהֵיהֶֽן

and thou take of their daughters unto thy sons, and their daughters go astray after their gods, and make thy sons go astray after their gods.

אֶת־חַג הַמַּצּוֹת תִּשְׁמֹר שִׁבְעַת יָמִים תֹּאכַל מַצּוֹת אֲשֶׁר צִוִּיתִךָ לְמוֹעֵד חֹדֶשׁ הָאָבִיב כִּי בְּחֹדֶשׁ הָֽאָבִיב יָצָאתָ מִמִּצְרָֽיִם

The feast of unleavened bread shalt thou keep. Seven days thou shalt eat unleavened bread, as I commanded thee, at the time appointed in the month Abib, for in the month Abib thou camest out from Egypt.

כָּל־פֶּטֶר רֶחֶם לִי וְכָֽל־מִקְנְךָ תִּזָּכָר פֶּטֶר שׁוֹר וָשֶֽׂה

All that openeth the womb is Mine; and of all thy cattle thou shalt sanctify the males, the firstlings of ox and sheep.
