The aggadic expositions in the Mekhilta, which are found chiefly in "Beshallah" and "Yitro" are in part actual exegesis, but the majority of them are merely interpretations of Scripture to illustrate certain ethical and moral tenets. Parables are frequently introduced in connection with these interpretations as well as proverbs and maxims. Especially noteworthy are the aggadot relating to the battles of the Ephraimites and to Serah, Asher's daughter, who showed Joseph's coffin to Moses, besides others, which are based on old tales and legends.
