2 And Joab sent to Tekoa, and fetched thence a wise woman, and said unto her, I pray thee, feign thyself to be a mourner, and put on mourning apparel, I pray thee, and anoint not thyself with oil, but be as a woman that hath a long time mourned for the dead: 3 and go in to the king, and speak on this manner unto him. So Joab put the words in her mouth. 4 And when the woman of Tekoa spake to the king, she fell on her face to the ground, and did obeisance, and said, Help, O king.

Commentary on 2 Samuel 14:1-20
(Read 2 Samuel 14:1-20)
We may notice here, how this widow pleads God's mercy, and his clemency toward poor guilty sinners. The state of sinners is a state of banishment from God. God pardons none to the dishonour of his law and justice, nor any who are impenitent; nor to the encouragement of crimes, or the hurt of others.
