1 Samuel 26:15-16

ASV_Strongs(i)
  15 H1732 And David H559 said H74 to Abner, H376 Art not thou a valiant man? H3478 and who is like to thee in Israel? H8104 wherefore then hast thou not kept H113 watch over thy lord H4428 the king? H935 for there came H259 one H5971 of the people H7843 in to destroy H4428 the king H113 thy lord.
  16 H1697 This thing H2896 is not good H6213 that thou hast done. H3068 As Jehovah H2416 liveth, H1121 ye are worthy H4194 to die, H8104 because ye have not kept H113 watch over your lord, H3068 Jehovah's H4899 anointed. H7200 And now see H4428 where the king's H2595 spear H6835 is, and the cruse H4325 of water H4763 that was at his head.
