Jeremiah 3:24,25 - Joseph Benson’s Commentary on the Old and New Testaments

For shame hath devoured the labour of our fathers That is, the fruit of their labour, יגיע, which properly signifies labour and toil, being here put by a metonymy for the substance acquired by toil; that is, their labours have been followed by disappointment and shame; they have not reaped the expected fruit of them. Or sin, which causes shame, especially the sin of idolatry, has brought all our calamities upon us, the loss of our goods and substance, the dispersion of our families and nearest relations, and all the other miseries of our captivity: all these evils, which we and our forefathers have felt, are the effects of our idolatry, of which we are now heartily ashamed, and which had brought shame and confusion upon us. Blaney renders הבשׁת, (which we translate shame,) that thing of shame, meaning the idol which they worshipped, called by the same name, chap. Jeremiah 11:13; Hosea 10:10; “and with good reason,” says he, “because, in return for all the expense and pains bestowed upon it, it only frustrated the hopes of its votaries, and, as it follows in the next verse, left them mortified with disappointment, and overwhelmed with disgrace, for having deserted the service of a Being that could have saved them, in pursuit of so vile and worthless an object.” We lie down in our shame Being unable to bear it. Our confusion covereth us On account both of our sins and sufferings. Sin hath laid us under such rebukes of God's providence, and such reproaches of our own consciences, as surround us and fill us with shame. These expressions, which set forth the greatness of their repentance and sorrow, are taken from those who cast themselves down upon the ground, and cover themselves with dust or ashes, out of grief and anguish of mind.
