1 Samuel 19:6 - Coke's Commentary on the Holy Bible

And Saul sware, As the Lord liveth, he shall not be slain— To judge of Saul by his future conduct, we should be tempted to believe, that he swore only the better to deceive his son Jonathan. But when we consider well the character of this prince, weak, inconstant, passionate, we may suppose, without much difficulty, that the discourse of Jonathan affected him, and that he sincerely resolved no more to attack the life of David: a resolution, however, which David's increasing glory soon overthrew, 1 Samuel 19:8.
