Matthew Poole and continuators on Jeremiah 8:4

4 ¶ Moreover, thou shalt say i unto them, thus saith the LORD, shall they fall, and not arise? shall he turn away, and not return?

An interrogation that hath the force of a negative, i. e. surely none, or will men, is there no hope? and are they upon this ground desperate? Or rather will men fall and not arise? Are they such fools? that having fallen by their sins, and been foretold all that is coming, that they will not accept of a remedy, chap. 7.27. Hos. 14.1.

A metaphor taken from one that is out of his way, can any imagine, that if one tell him of it, and direct him aright, that he will not hearken to him, and turn back? It is even against nature it self for a man not to seek his own good.

Though possibly it be all in vain, yet thou shalt keep in thy work.
