Midras Ulangan 16:16: Ein Yaakov (Glick Edition), Mekhilta DeRabbi Yishmael, Midrash Tanchuma & Eikhah Rabbah

שָׁל֣וֹשׁ פְּעָמִ֣ים ׀ בַּשָּׁנָ֡ה יֵרָאֶ֨ה כָל־זְכוּרְךָ֜ אֶת־פְּנֵ֣י ׀ יְהוָ֣ה אֱלֹהֶ֗יךָ בַּמָּקוֹם֙ אֲשֶׁ֣ר יִבְחָ֔ר בְּחַ֧ג הַמַּצּ֛וֹת וּבְחַ֥ג הַשָּׁבֻע֖וֹת וּבְחַ֣ג הַסֻּכּ֑וֹת וְלֹ֧א יֵרָאֶ֛ה אֶת־פְּנֵ֥י יְהוָ֖ה רֵיקָֽם׃

Tiga kali setahun setiap laki-laki di antaramu harus menghadap ke hadirat Yang Mahakekal, Allahmu, di tempat yang akan dipilih-Nya, yaitu pada Hari Raya Roti Tidak Beragi, pada Hari Raya Tujuh Minggu, dan pada Hari Raya Pondok Daun; dan janganlah ia menghadap ke hadirat Yang Mahakekal dengan tangan hampa;

Ein Yaakov (Glick Edition)

(Fol. 4b) R. Juda says: "A man blind on one eye is exempt from the holocaust, because it is said (Deut. 16, 16) Shall appear; just as if one comes to see, it is with both eyes, so if he comes to be seen, he must have both his eyes."

Mekhilta DeRabbi Yishmael

(Exodus 12:2) "The beginning of the months": We are hereby apprised that Nissan is the beginning for the months. And whence do we derive (the same for) the reign of kings? From (I Kings 6:1) "In the fourth year of Solomon's reign over Israel, in the month of Ziv (Iyyar), the second month," (his reign having begun with the first month, Nissan). And whence do we derive (the same for) festivals (i.e., that one is not in transgression of delaying his vows until three consecutive festivals have passed)? From (Devarim 16:16) "… the festival of matzoth (in Nissan), and the festival of Shavuoth, and the festival of Succoth." We find, then, that Nissan is the beginning for months, for kings, and for festivals.

Mekhilta DeRabbi Yishmael

(Exodus 23:14) "Three festivals shall you celebrate for Me in the year": What is the intent of this? Because it is written (Ibid. 17) "Three times, etc.", I might think at whatever place or time that one wishes; it is, therefore, written (Devarim 16:16) "on the festival of Matzoth, and the festival of Shavuoth, and the festival of Succoth." (Exodus 23:17) "shall be seen" (yod, resh, alef, heh, [which can also be read as "shall see"])
