Moses led Israel away: lit., made Israel journey. He led them away against their will, for the Egyptians had adorned their steeds with ornaments of gold, silver, and precious stones, and the Israelites were finding them in the sea. The plunder at the sea was greater than the plunder in Egypt, as it is said: “We will make you rows of gold with studs of silver” (Song of Songs 1:11). Therefore, he had to lead them against their will.
But in Shemot 12:36, Rashi says:
and they emptied out: Heb. וַיְנַצְלוּ. Onkelos renders: וְרוֹקִינוּ, and they emptied out.
Furthermore, in Bereshit 45:18, Rashi describes the emptying of Egypt as:
the best of the land of Egypt: [I.e.,] the land of Goshen. He prophesied but did not know what he was prophesying. They (the Israelites) would eventually make it (Egypt) like the depths of the sea, which have no fish. [From Avoth d’Rabbi Nathan, second version, ch. 43; Ber. 9b]
My question is, if the Jews emptied out Egypt before they left, where did all the "gold, silver, and precious gems" which the Egyptians adorned their steeds with come from?
On the other hand, if the Jews left more gold in Egypt than they took with them, how can we consider what the Jews did "emptying the land of Egypt"?
