Haggadah: Mukdam u’Me-uchar: Seder
The 7th of Nisan is the Yahrtzeit of Rav Aryeh Leib Yelin (ben Shalom Shachna) of Bialystock (1820-1884[or 1886]). Born in Yasinovka, He is the author of Yefeh Einayim, which lists sources, parallel passages, and variant readings in midrashim and in the aggadah of the gemara and draws attention to differences between the Bavli and Yerushalmi. He was also the author of Mitzpeh Aryeh, short notes on the Rif, and of Kol
Aryeh, further drashos on the Mitzpeh Aryeh. The Penei Aryeh is a comprehensive
commentary on the Yerushalmi.
Rav Yellin also published a short book, “Mukdam u’Meuchar, or, “What comes first,” in which he explores the order of some basic ideas such as the source of the Aleph Bet and its order; when are blessings mentioned before curses and when are the curses mention first; when are fathers mention first, and when mothers; and much more.
“I found ten thousand topics in Tanach, Talmud, and Midrash, in which the issue of the order in which words appear is mentioned. I have worked assiduously to explore this question, and find that there are always great secrets in the reason for a change in the order.”
