Jeremiah 8:4

Moreover, thou shalt say unto them
The Jews, in Jeremiah's time, in order to leave them inexcusable, though the Lord had before assured that they would not hearken to him, ( Jeremiah 7:27 ) : thus saith the Lord, shall they fall, and not rise?
men, when they fall, endeavour to get up again, and generally they do: shall he turn away, and not return?
when a man turns out of the right way into a wrong one, as soon as he is sensible of his mistake, he returns back; this is usually done among men. This is generally the case in a natural sense, and might be expected in a moral sense; that whereas these people had fallen into sin, they would rise again by repentance; and, having turned from the good ways of God, would soon return again to them.
