The Koren Talmud Bavli, Noé Edition, Vol 17: Ketubot Part 2, Daf Yomi B&W

Ketubot is the central tractate in the order of Nashim. It provides clarification of most of the matters that constitute the relationship between husband and wife: Conjugal relations, mutual obligations, and monetary arrangements between them. In a general sense it addresses the entirety of marital life. Due to the abundance and variety of the topics, which branch out into many different areas of halakha, the early commentaries called tractate Ketubot the miniature Talmud or the key to the Talmud.  Begins: Perek VI . 65b
