“And on the eighth day he shall bring two turtledoves or two young pigeons, to the priest, to the entrance of the Tent of Meeting” (Numbers 6:10). “And on the eighth day” – to exclude the seventh, or is it to exclude the ninth? “Eighth” is stated here and “eighth” is stated elsewhere: “And from the eighth day on” (Leviticus 22:27). Just as “eighth” stated elsewhere, it allowed in that regard the eighth and from the eighth on, so, too, “eighth” stated here allows in its regard the eighth and from the eighth on.
Had it said “turtledoves,” would it be, perhaps, many? The verse states: "He shall bring two turtledoves” – I said only two. May one, perhaps, bring turtledoves and young pigeons? The verse states: “Or two young pigeons.”
May one, perhaps, bring one young bird from this and one young bird from that? The verse states: “He shall bring two turtledoves or two young pigeons.” From here they said: One does not bring a turtledove opposite a young pigeon, nor a young pigeon opposite a turtle dove.123One may not bring one as a burnt offering and one as a sin offering. “To the priest, to the entrance of the Tent of Meeting,” it teaches that one must tend to those he is bringing until he brings them to the entrance of the Tent of Meeting.
