2 Samuel 14:9

²⁴She fell at his feet and said, “On me, my lord, on me be the blame! Please let your servant speak in your ears. Hear the words of your servant.

³³So their blood will return on the head of Joab and on the head of his offspring^[+] forever. But for David, for his offspring, for his house, and for his throne, there will be peace forever from the LORD.”

²⁵All the people answered, “May his blood be on us and on our children!”

¹³His mother said to him, “Let your curse be on me, my son. Only obey my voice, and go get them for me.”

¹If someone is found slain in the land which the LORD your God gives you to possess, lying in the field, and it isn’t known who has struck him, ²then your elders and your judges shall come out, and they shall measure to the cities which are around him who is slain. ³It shall be that the elders of the city which is nearest to the slain man shall take a heifer of the herd, which hasn’t been worked with and which has not drawn in the yoke. ⁴The elders of that city shall bring the heifer down to a valley with running water, which is neither plowed nor sown, and shall break the heifer’s neck there in the valley. ⁵The priests the sons of Levi shall come near, for them the LORD your God has chosen to minister to him, and to bless in the LORD’s name; and according to their word shall every controversy and every assault be decided. ⁶All the elders of that city which is nearest to the slain man shall wash their hands over the heifer whose neck was broken in the valley. ⁷They shall answer and say, “Our hands have not shed this blood, neither have our eyes seen it. ⁸Forgive, LORD, your people Israel, whom you have redeemed, and don’t allow innocent blood among your people Israel.” The blood shall be forgiven them. ⁹So you shall put away the innocent blood from among you, when you shall do that which is right in the LORD’s eyes.

²⁸Afterward, when David heard it, he said, “I and my kingdom are guiltless before the LORD forever of the blood of Abner the son of Ner. ²⁹Let it fall on the head of Joab and on all his father’s house. Let there not fail from the house of Joab one who has a discharge, or who is a leper, or who leans on a staff, or who falls by the sword, or who lacks bread.”

³³“‘So you shall not pollute the land where you live; for blood pollutes the land. No atonement can be made for the land for the blood that is shed in it, but by the blood of him who shed it.
