Jeremiah 5:3 - Matthew Poole's English Annotations on the Holy Bible

Are not thine eyes upon the truth? The prophet, observing the obstinacy of this people, abruptly turns himself to God, yet emphatically insinuates their incorrigibleness. This may refer either to God's discerning and knowing truth from falsehood, as being impossible that any thing should be hid from him, Psalms 11:4; or rather, (more agreeably to the phrase,) to God's approving; and this some again refer to persons, as men of truth for true men, so man of wisdom for a wise man, Micah 6:9; but others, better, to truth and faithfulness, as that which God hath a great respect for, and delight in, Psalms 51:6, and was not to be found among these people. Though none of these senses be improper, this seems the most genuine. They have not grieved; they have been under sore grievances that God hath laid them under, yet they seem unconcerned, Proverbs 23:35 Isaiah 42:25; or it is probable they were grieved at their sufferings, but they have not repented, thereby to turn away the causes of his just displeasure: see 2 Corinthians 7:9,10. Thou hast consumed them; God had not only lightly chastised them, but wasted them by several enemies, as the Assyrian, Isaiah 10:5,6 Isaiah 36:1, and Pharaoh-nechoh, 2 Kings 23:33, and the Chaldees, Syrians, Moabites, and the Ammonites, 2 Kings 24:2, and Nebuchadnezzar, 2 Kings 24:13, &c. All these he made use of as the rod of his indignation, yet they refused to receive correction; see Jeremiah 2:30; a metonymy of the effect; they have profited nothing by it, not at all reformed, Isaiah 1:5,16 Am 4:6,8-11. They have made their faces harder than a rock; noting their obstinacy and impudence, laying aside all sense of judgments, as past feeling, Proverbs 21:29 Malachi 7:12. They have refused to return; wilfully rejected counsel, and slighted correction, resolving to persist in their obstinacy.
