2 Samuel 14:5-11

5 The king asked her, “What is troubling you?”
She said, “I am indeed a widow; my husband is dead.

6 I your servant had two sons. They got into a fight with each other in the field, and no one was there to separate them. One struck the other and killed him.

7 Now the whole clan has risen up against your servant; they say, ‘Hand over the one who struck his brother down, so that we may put him to death for the life of his brother whom he killed; then we will get rid of the heir as well.’ They would put out the only burning coal I have left, leaving my husband neither name nor descendant on the face of the earth.”

8 The king said to the woman, “Go home, and I will issue an order in your behalf.”

9 But the woman from Tekoa said to him, “My lord the king, let the blame rest on me and on my father’s family, and let the king and his throne be without guilt.”

10 The king replied, “If anyone says anything to you, bring him to me, and he will not bother you again.”

11 She said, “Then let the king invoke the Lord his God to prevent the avenger of blood from adding to the destruction, so that my son will not be destroyed.”
“As surely as the Lord lives,” he said, “not one hair of your son’s head will fall to the ground.”
