2 Samuel 11:14

David wrote a letter to Joab.

--So in the Greek story, Proetus sent Bellerophon to Jobates with his own death warrant. (Cp. Hom. II. 6:168, 169.) “Slay him he would not, that his soul abhorred; but to the father of his wife, the King of Lycia, sent him forth, with tokens charged of dire import, on folded tablets traced, poisoning, the monarch’s mind to work his death.” (A. F. Kirkpatrick, M. A.)
