It addresses the law concerning two people who said, "Let's give a blessing." It explains what wine is blessed for: "Whoever is good and shows kindness to others." It addresses whether the blessing should be recited over something that was not in front of them or that fell from their hand into the sea. It addresses those who are standing before a stream of water and reciting a blessing. It covers foods that are served within a meal. It addresses those who recite the blessing over wine before a meal, and whether the blessing over wine after the bread should be excluded.
