Seeing as the Korban Pesach must be a lamb or a kid-goat, why does the Torah add the word "u'Bakar"?
Rashi (citing Targum Onkelos) and Rashbam #1: "Bakar" refers to the Chagigah of the fourteenth that one brings together with the Korban Pesach if the group is a large one, to enable the Pesach to be eaten to satiation. 1
Ramban, Rashbam #2 and Targum Yonasan: "Tzon u'Bakar" refers to the Chagigah of Yom-Tov 2 that one brings on the fifteenth or throughout the Yom-Tov, which can consist of "Tzon" (sheep and goats) or cattle. 3
Pesachim, 70b: To teach us that 'Mosar ha'Pesach' (a Korban Pesach that was not brought on Pesach) 4 must be brought as a Shelamim - which can comprise either Tzon or Bakar. 5
Whereas "Tzon" refers to the Korban Pesach mentioned in the previous Pasuk. See Seforno, who also seems to learn like this. See Ramban's objection to this explanation.
Ramban: Like the Chagigah that one brings on Shavu'os and Sukos.
Ramban: And it is as if the Torah had written "ve'Tzon u'Bakar (with a 'Vav'), like we find above in 14:4 and in Sh'mos, 1:20. See Ramban, who elaborates. See Oznayhim la'Torah, who asks that the Torah should have mentioned "Bakar" before "Tzon"?
See Torah Temimah, note 6.
See Toqrah Temimah, Ibid., who elaborates.
Having already taught the Korban Pesach in Bo, why does the Torah repeat it here?
