אֶת־חַ֣ג הַמַּצּוֹת֮ תִּשְׁמֹר֒ שִׁבְעַ֨ת יָמִ֜ים תֹּאכַ֤ל מַצּוֹת֙ אֲשֶׁ֣ר צִוִּיתִ֔ךָ לְמוֹעֵ֖ד חֹ֣דֶשׁ הָאָבִ֑יב כִּ֚י בְּחֹ֣דֶשׁ הָֽאָבִ֔יב יָצָ֖אתָ מִמִּצְרָֽיִם׃
Ipangilin mo ang Pista ng Tinapay na Walang Lebadura. Pitong araw kang kakain ng tinapay na walang lebadura, gaya ng iniutos ko sa iyo, sa takdang panahon ng buwan ng Abib, sapagkat sa buwan ng Abib ka lumabas mula sa Egipto.
Rashi
חדש האביב THE MONTH OF ABIB — the month of early ripening — the month when the grain is in its first stage of ripening.
Chizkuni
את חג המצות, the festival of matzot, etc.; all the commandments listed in this paragraph up to and including verse 26, are symbols of the fact that you have become servants of Hashem and that on the festivals named, the servants present their master with a gift expressing their fondness of |Him as well as their subservience.
Da'at Zekenim
את חג המצות “the festival of unleavened bread, etc.;” the festivals are repeated in order to warn the people not to add a festival of their own as they had done when they danced around the golden calf. This is the reason that these festivals’ names follow immediately upon the reminder not to make a molten image.
