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
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; (See Gill on Leviticus 13:2), (See Gill on 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 ) ( Revelation 16:10 Revelation 16:11 ) .
