1 Samuel 25:29 Yet a man is risen to pursue thee, and to seek thy soul: but the soul of my lord shall be bound in the bundle of life with the Lord thy God; and the souls of thine enemies, them shall he sling out, as out of the middle of a sling.

1 Samuel 20:3 Then David took an oath again, and said, “Your father certainly knows that I have found favor in your eyes, and he has said, ‘Do not let Jonathan know this, lest he be grieved.’ But truly, as the Lord lives and as your soul lives, there is but a step between me and death.”

1 Samuel 16: 7 But the Lord said to Samuel, “Do not look at his appearance or at his physical stature, because I have refused him; for the Lord does not see as man sees, for man looks at the outward appearance, but the Lord looks at the heart.”
