One of the amazing things about the Exodus is that the Children of Israel were more likely, when they left Egypt, to be found with a cache of loose diamonds on them, rather than with, say, a bunch of swords.
That’s what makes their victory in escape such a testimony to God. After all, without the L-RD, they would have been sitting ducks, rather than a people who crossed a sea bed on dry ground. That’s pretty amazing, which is what the L-RD wanted it to be: a testimony to His existence.
