Deuteronomy 7:15

And will take away from thee all sickness,.... Bodily sickness and diseases, prevent the coming of them, or remove them when come:

and will put none of the evil diseases of Egypt which thou knowest upon thee; meaning either the plagues that were inflicted upon them to oblige them to let the Israelites go, of which they had perfect knowledge; or else some noxious and nauseous diseases, which were common among, and peculiar to, the Egyptians, particularly what is called the botch of Egypt; see Exodus 15:26, likewise the leprosy;

Leviticus 13:2,

Deuteronomy 28:27.

but will lay them upon all them that hate thee; with which God sometimes punishes his and his people's enemies; see Judges 5:9.
