Jeremiah 18:12

And they said, There is no hope: but we will walk after our own devices, and we will every one do the imagination of his evil heart.

They said, There is no hope - thy threats and exhortations are all thrown away ). Our case is desperate; we are hopelessly abandoned to our sins and their penalty. In this and the following clauses, "We will walk after our own devices," Jeremiah makes them express the real state of the case, rather than the hypocritical subterfuges which they would have been inclined to put forth. So Isaiah 30:10.
