Rav Shmueli: Buy 2 suits to greet Mashiah
Rav Shmueli, in his weekly shiur, talks a lot about how one must prepare for the seder night. It's worth listening to the whole thing for those who understand Hebrew.
Here's a clip of that shiur, to which I added subtitles, where he mentions that one should buy 2 new suits - 1 for Birkat Hahama and 1 for Pesah - so that we can say shehehiyanu on them, so we perhaps can merit to greet Mashiah.
Sorry for the "static" in the video. It was in the original.
