I received the following question:

Exodus 12:38. A mixed multitude went up with them also, and flocks and herds—a great deal of livestock.

Are these non-Israelites or Egyptians who feared the lord?

I do not believe that the “mixed multitude” were Israelites. There were probably a good number of Egyptians among them, but there might have been some from other nations, particularly nations that were allies with or more or less subservient to Egypt at this time. This mixed multitude might not have considered the LORD their God as much as the Hebrews did, and they became a source of trouble at least once (Numbers 11:4).
