With regard to a woman’s bill of divorce, Deuteronomy 24:1 states: “And he shall write to her, he who does not

(the bill should be written) on a substance that is lacking only to be given.

This excludes a bill of divorce that is written while the article on which it is written is attached and afterwards detached. For it is lacking both being detached and being given.

Similarly, with regard to a bill of release, it is written: “given to her,” (Lev 19:2) teaching that the bill of release should be lacking only being given.
