Deuteronomy 28:60

Moreover, he will bring upon thee all the diseases of Egypt,.... All that in a way of judgment were brought upon the Egyptians for refusing to let Israel go; or all such diseases as were peculiar to them, and common among them, as the leprosy, the itch, ulcers, c.

which thou wast afraid of when living among them, lest they should catch them of them, or they should be inflicted on them by the hand of God:

and they shall cleave unto thee; not only should come upon them, but continue with them; they should not easily get rid of them, or be cured of them.
