2 Samuel 3:27-29 Living Bible (TLB)
27 When Abner arrived at Hebron, Joab took him aside at the city gate as if to speak with him privately; but then he pulled out a dagger and killed him in revenge for the death of his brother Asahel.
28 When David heard about it he declared, “I vow by the Lord that I and my people are innocent of this crime against Abner. 29 Joab and his family are the guilty ones. May each of his children be victims of cancer, or be lepers, or be sterile, or die of starvation, or be killed by the sword!”
