Rashi
your name for an oath From your name shall be taken a curse and an oath for generations, “If it does not befall me as it befell So-and-so.”
Ibn Ezra
And ye shall leave your name for a curse. Comp.17The Hebrew text has the words ואלה כמו; and a curse, comp. ואלה is either the explanation of לשבועה and must be altered into לאלה, or it is the remnant of a quotation, and must in that case be preceded by כמו. The Lord make thee a curse and an oath (Num. 5:21); The Lord make thee like Zedekiah and like Ahab (Jer. 29:22). The Lord God shall slay thee. Thus they will say to each other.18This explanation is given on account of the change of the number; the suffix in שמכם is plural, while that of והמיתך is singular. In Targum Jonathan it is rendered, וימיתכון and shall kill you.
Rashi
but to His servants He shall call another name A good name and a mention for a blessing.
