Charles Ellicott Commentary Numbers 11:4

"And the mixed multitude that was among them lusted exceedingly: and the children of Israel also wept again, and said, Who shall give us flesh to eat?" — Numbers 11:4 (ASV)

And the mixed multitude.— The Authorised Version follows the Septuagint and the Vulgate in rendering the word asaph-suph, which occurs only in this place, and which is derived from a verb that means to collect, in the same way as the ereb of Exodus 12:38, a mixed multitude, vulgus promiscuum—in many cases, probably, the children of Hebrew women by Egyptian fathers. This mixed multitude appears to have been very considerable, and they may have become, as the Gibeonites at a later period, servants to the Israelites, as hewers of wood and drawers of water (Deuteronomy 29:11).

It is probable that this mixed multitude may have partaken even more largely than the Israelites of the fish and vegetables of Egypt, and they appear to have instigated the Israelites to repine at the deprivations to which they were exposed in the wilderness. There is no mention in Exodus 16:3 of weeping, but the same craving after the flesh-pots of Egypt was probably manifested in the same manner in both cases.

Who shall give us flesh to eat?—The word basar, which is rendered flesh, seems here to include—it may be to have primary reference to—fish. It is used of fish in Leviticus 11:11, and it is obvious from Numbers 11:22 that it was understood by Moses in this general signification. Compare to the use of flesh (1 Corinthians 15:39).
