20:14-18 When grace has the victory, it is good to be ashamed of our folly, to admire the goodness of God, and be warned to guard our spirits another time. See how strong the temptation was, over which the prophet got the victory by Divine assistance! He is angry that his first breath was not his last. While we remember that these wishes are not recorded for us to utter the like, we may learn good lessons from them. See how much those who think they stand, ought to take heed lest they fall, and to pray daily, Lead us not into temptation. How frail, changeable, and sinful is man! How foolish and unnatural are the thoughts and wishes of our hearts, when we yield to discontent! Let us consider Him who endured the contradiction of sinners against himself, lest we should be at any time weary and faint in our minds under our lesser trials.

14-18. The contrast between the spirit of this passage and the preceding thanksgiving is to be explained thus: to show how great was the deliverance (Jer 20:13), he subjoins a picture of what his wounded spirit had been previous to his deliverance; I had said in the time of my imprisonment, "Cursed be the day"; my feeling was that of Job (Job 3:3, 10, 11, whose words Jeremiah therefore copies). Though Jeremiah's zeal had been stirred up, not so much for self as for God's honor trampled on by the rejection of the prophet's words, yet it was intemperate when he made his birth a subject for cursing, which was really a ground for thanksgiving.
