¹ tn The “mixed multitude” (עֵרֶב רַב, ʿerev rav) refers to a great “swarm” (see a possible cognate in 8:21 [17]) of folk who joined the Israelites, people who were impressed by the defeat of Egypt, who came to faith, or who just wanted to escape Egypt (maybe slaves or descendants of the Hyksos). The expression prepares for later references to riffraff who came along.

² tn The mixed multitude (or “rabble,” so NASB, NIV, NRSV; NLT “foreign rabble”) is the translation of an unusual word, הָאסַפְסֻף (haʾsafsuf). It occurs in the Hebrew Bible only here. It may mean “a gathering of people” from the verb אָסַף (ʾasaf), yielding the idea of a mixed multitude (in line with Exod 12:38). But the root is different, and so no clear connection can be established. Many commentators therefore think the word is stronger, showing contempt through a word that would be equivalent to “riff-raff.”
