창세기 29:27 할라카: Kitzur Shulchan Arukh

It is forbidden to perform the marriage ceremonies of two brothers or of two sisters in the same day, because you may not join one festive event with another. Some [authorities] say that you may not perform both ceremonies even in the same week,¹⁷Taz 548:1—Rabbeinu Yehudah Hachassid. See Sha’ar Hatziyun 546:3 who rules against this opinion, for Rashal stated it is a printing error as it contradicts the Talmud that permits one to marry less than a week before Yom Tov. and they bring proof [of this from the marriage] of our father, Yaakov. For it is written, "Fulfill the week of this one."¹⁸Genesis 29:27.
