Babylonian Talmud Pesahim deals with regulations for the Passover holiday, prohibitions of leavened food and prescriptions for the Paschal lamb. It is the third treatise of the order Mo'ed. It is divided into ten chapters.
Chapter ten deals with the Seder meal eaten on the evening of Passover; the four cups of wine, and the benedictions pronounced over them; the questions of the son and the father's answers and instructions; other benedictions and the Hallel.
