Local to this pasuk, it makes a lot of sense on a peshat level. That is, the second pasuk explains, in part, the taking out of the Israelites with a high hand to the sight of all the Egyptians. They were busy with their burying and mourning.
It struck me that there is a parallel here to parshat Shelach, by the report of the meraglim. In Bemidbar 13:32:
Rashi, citing a derasha from Rava in Sotah, explains:
consumes its inhabitants Wherever we passed, we found them burying dead. The Holy One, blessed is He, intended this for good, to keep them occupied with their mourning so they should not notice them [the spies]. — [Sotah 35a]It may well be that their entrance into the land was to parallel their exiting of Egypt, and this is where Rava borrowed his idea in this midrash.
