The 359th prohibition is that the motzi shem ra is forbidden from divorcing his wife.

The source of this commandment too1 is G‑d's statement,2 "he may not send her away as long as he lives."

This prohibition is also3 preceded by a positive command, "he must then take her as his wife."

Should he divorce his wife, the law regarding lashes is like that of the rapist,4 as explained in the last chapter of Makkos.5 The details of this mitzvah are explained there, and in the third and fourth chapters of Kesubos.
