Charles Ellicott Commentary Jeremiah 5:3

"O Jehovah, do not thine eyes look upon truth? thou hast stricken them, but they were not grieved; thou hast consumed them, but they have refused to receive correction: they have made their faces harder than a rock; they have refused to return." — Jeremiah 5:3 (ASV)

Upon the truth. —The Hebrew word, which has no article, implies truth in the inward parts, faithfulness, as well as truth in words. The “eyes” of God looked for this, and He found the temper that hardens itself against discipline, and refuses to repent.
