2 Samuel 3:28-30 Living Bible (TLB)
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!”
30 So Joab and his brother, Abishai, killed Abner because of the death of their brother, Asahel, at the battle of Gibeon.
