1 Samuel 25:32-33

Blessed be the Lord, &c. Who, by his gracious providence, so disposed matters that thou shouldst come to me. He rightly begins at the fountain of this deliverance; and then proceeds to the instruments. Who hast kept me from coming, &c. Which I had sworn to do. Hereby it plainly appears, that oaths, whereby men bind themselves to any sin, are null and void; and, as it was a sin to make them, so it is adding sin to sin to perform them.
