The 5th chapter ends with a discussion of how the Jews sang the song on the Red Sea with Moshe. And whether Job worshipped God out of love or out of fear. The 6th Chapter begins with how many witnesses and what types of witnesses are needed for the seclusion stage of the Sotah process (setira)? Can a testimony from a bird be sufficient? Once the first two stages are well established (kinui and setira – the husband’s warning to his wife and then her seclusion), if a lesser form of testimony confirms that during the seclusion, the couple has relations, the woman cannot drink the Sotah waters and is forever forbidden to her husband. The mishna also discusses the law in cases where there was conflicting testimony regarding whether or not they had relations.
