2 Samuel 3:26
King James Version
“And when Joab was come out from David, he sent messengers after Abner, which brought him again from the well of Sirah: but David knew not.”
Context
23When Joab and all the host that with him were come, they told Joab, saying, Abner the son of Ner came to the king, and he hath sent him away, and he is gone in peace.
24Then Joab came to the king, and said, What hast thou done? behold, Abner came unto thee; why it thou hast sent him away, and he is quite gone?
25Thou knowest Abner the son of Ner, that he came to deceive thee, and to know thy going out and thy coming in, and to know all that thou doest.
26And when Joab was come out from David, he sent messengers after Abner, which brought him again from the well of Sirah: but David knew not.
27And when Abner was returned to Hebron, Joab took him aside in the gate to speak with him quietly, and smote him there under the fifth that he died, for the blood of Asahel his brother.
28And afterward when David heard he said, I and my kingdom guiltless before the LORD for ever from the blood of Abner the son of Ner:
29Let it rest on the head of Joab, and on all his father’s house; and let there not fail from the house of Joab one that hath an issue, or that is a leper, or that leaneth on a staff, or that falleth on the sword, or that lacketh bread.
