Mixed multitude

(Ex. 12:38), a class who accompanied the Israelites as they journeyed from Rameses to Succoth, the first stage of the Exodus. These were probably miscellaneous hangers-on to the Hebrews, whether Egyptians of the lower orders, or the remains of the Hyksos (see EGYPT �T0001137; MOSES �T0002602), as some think. The same thing happened on the return of the Jews from Babylon (Neh. 13:3), a "mixed multitude" accompanied them so far.
