Rashi on Leviticus 7:16/רש"י על ויקרא ז׳:ט״ז

1ואם נדר או נדבה BUT IF [THE SACRIFICE OF HIS OFFERING BE] A VOW OR A FREE WILL OFFERING — i. e., that he does not bring it as an acknowledgement of some miraculous deliverance (cf. Rashi v. 12), then it does ‘not require the offering of bread and may be eaten during two days as is set forth in the section.

2וממחרת והנותר ממנו AND ON THE MORROW ALSO THE REMAINDER OF IT — i. e. what remained on the first day, יאכל MAY BE EATEN; — this ו (that of והנותר) is redundant (the text being equivalent to וממחרת הנותר ממנו יאכל); there are many similar examples in Scripture: (Genesis 36:24) “And these are the sons of Zibean: And Ajah (ואיה) and Anah”; (Daniel 8:13): “to give and the Sanctuary (וקדש) and the host to be trampled under foot”.
