1 Samuel 19:6
And Saul hearkened unto the voice of Jonathan: and Saul sware, As the LORD liveth, he shall not be slain.
And Saul hearkened unto the voice of Jonathan,.... Not only heard him out what he had to say, but was affected with it, and wrought upon by it, and was convicted for the present that he was wrong in seeking the life of David, and therefore would desist from it; the Lord working upon his mind by what Jonathan said, and inclined him to listen to it, and act accordingly:
and Saul sware, As the LORD liveth, he shall not be slain; this oath he added to what he said to Jonathan, for the confirmation of it; and which was taken either with a real intention to keep it, though that intention did not long continue; or with a view to deceive Jonathan, that he might acquaint David with it, and so prevent his flight and escape, and that he might the more easily fall into his hands; but the former seems rather to be the case.
