What are the connotations of the word "Hinei"?
Rashi: It can be compared to a king who gave his friend a field, and, when someone claimed that the field was his, the king said to the friend 'Let people say what they want; I am going to write a Sh'tar on the sale, sign it and have the court authenticate it.
