What are the connotations of "Shalosh Regalim"?
Rashi, R. Bachye #1, Targum Onkelos and Targum Yonasan: It means three times a year. 1
R. Bachye #2 and Chagigah 4a: It means three foot-festivals, on which one is obligated to go up to the Beis-ha'Mikdash on foot. Consequently, someone who has a wooden leg, 2 who is lame (even in one leg - Chagigah, 3a) sick, blind, old or who is unable to walk (or a Katan who is unable to hold his father's hand and ascend Har ha'Bayis together with him 3 - Chagigah, 2a) is exempt from Aliyas ha'Regel on Yom-Tov ah - Chagigah, 2a).
R. Bachye #3 (citing Pesikta Zutr'sa): It teaches us that one is Chayav to go to Yerushalayim on Yom-Tov specifically on foot (and not on horsebck or on a wagon). 4 5
Chagigah 2a: A small child wwho is unable to hold his father's hand and walk to Yerulayaim - to the Har ha'Bayis - is Patur from the Mitzvah of Re'iyah. 6
As in Balak Bamidbar, 22:28 (Rashi).
See Torah Temimah, note 94. The Gemara there also learns it from the words "Shalosh Pe'amim" in Pasuk 16, which it equates with "Shalosh Regalim".
See Torah Temimah, note 92.
R. Bachye: As the Pasuk writes in Shir ha'Shirim 7:2 "Mah Yafu Pe'amayich ba'Ne'alim Bas N'div".
See R. Chavel's footnotes.
See note 2 on previous answer.
Why does the Torah insert the Shalosh Regalim in the Parshah of Sh'mitah?
What are the connotations of the words "Tachog Li"?
Seforno: It means 'Celebrate (rejoice) with Me (Hashem). 1
Targum Onkelos and Targum Yonasan: It means 'Celebrate before Me (Hashem)'.
As the Pasuk writes in Tehilim, 149:2, "Yismach Yisrael be'Osav" - as opposed to the Pasuk in Sh'mos 32:19 "Vayar es ha'Eigel u'Mecholos" (Seforno).
