Then the LORD will make thy plagues wonderful, and the plagues of thy seed, even great plagues, and of long continuance, and sore sicknesses, and of long continuance.

Commentary

Then the Lord will make thy plagues wonderful,.... Visible, remarkable, distinguishable, and astonishing to all that see them: and the plagues o f thy seed; for they were to continue, as they have done, With their posterity, age after age: even great plagues, and of long continuance; great as to quality and quantity, and firm, sure, lasting, and durable; the word used is rendered "sure" in Isa 55:3 ; sure by prophecy and in the event; and which when inflicted remained, as they have 1700 years; all which might be believed as certain, or what would certainly come to pass, and be depended on: and sore sicknesses, and of long continuance; besides those diseases mentioned Deu 28:27 ; or however others including them.
