The mixed multitude. Hebrew, ha-saphsuph, the gathered; the rift-raft, or rabble, which had followed the fortunes of Israel out of Egypt, where they had probably been strangers and slaves themselves.
What the nature and the number and the fate of this rabble were is a matter of mere conjecture and of some perplexity. There does not seem any room for them in the regulations laid down for Israel, nor are they mentioned in any other place except at Exodus 12:38.
In Le Exodus 24:10 we read of the son of an Israelitish woman by an Egyptian father, and this might lead us to conjecture that a great part of the "mixed multitude" was the offspring of such left-handed alliances.
These half-breeds, according to the general rule in such cases, would follow their mothers; they would be regarded with contempt by the Jews of pure blood, and would accompany the march as hangers-on of the various tribes with which they were connected.
As to their fate, it may be probably concluded, from the reason of things and from the absence of any further notice of them, that they found their way back to the slavery and the indulgences of Egypt; they were bound by no such strong restraints and animated by no such national feelings as the true people of the Lord.
And the children of Israel also wept again. This expression, again (Hebrew, שׁוּב, used adverbially), would seem to point to some former weeping, and this is generally found in the "murmuring" of which they had been guilty in the desert of Sin (Exodus 16:2, Exodus 16:3).
This, however, is unsatisfactory for several reasons: first, because that occurrence was too remote, having been more than a year ago; second, because there is no mention of any "weeping" at that time; third, because the matter of complaint on the two occasions was really quite different: then they murmured faithlessly at the blank starvation which apparently stared them in the face; now they weep greedily at the absence of remembered luxuries.
It is therefore much more likely that the expression has regard to the "complaining" which had just taken place at Tabeerah. It was indeed wonderful that the punishment then inflicted did not check the sin; wonderful that it burst out again in an aggravated form almost immediately.
But such was the obstinacy of this people, that Divine vengeance, which only perhaps affected a few, and only lasted for a brief space, was not sufficient to silence their wicked clamour. Who shall give us flesh to eat?
בָּשָׂר—Septuagint, κρέα—means flesh-meat generally. They had flocks and herds it is true, but they were no doubt carefully preserved, and the increase of them would little more than suffice for sacrifice; no one would dream of slaughtering them for ordinary eating.
