1 Samuel 26:16

16 this that thou hast done, is not good; the Lord liveth, for ye be sons of death, that kept not your lord, the christ of the Lord (this is not good, what thou hast done; as the Lord liveth, for ye be the sons of death, who kept not your lord safe, yea, the Lord's anointed). Now therefore see thou, where is the spear of the king, and where is the cup of water, that was at his head.

1 Samuel 26:16 Meaning and Commentary

1 Samuel 26:16

This thing [is] not good that thou hast done
Yea, it was very bad, a great fault, and very blameworthy, if he had neglected to set a watch over the king, whose business it was as a general; the words are expressed in a figure called "meiosis", in which less is said than was intended:

[as] the Lord liveth, ye [are] worthy to die, because ye have not kept
your master, the Lord's anointed;
if a watch was set, and these had fallen asleep, and neglected their duty, or had deserted their post; which to do was a capital crime, and deserving of death; wherefore he does not say this of Abner, but of the watch:

and now see where the king's spear [is], and the cruse of water that
[was] at his bolster;
which he then held up as proofs and evidences of the truth of what be said, that one had been in the camp and had carried off these, and who could as easily have destroyed the king as to have taken these away; and as he came hither with an intent to destroy him, would have done it, had he not been prevented by David; all which likewise plainly proved the negligence of Abner, in not setting a watch about his master, or the negligence of the watch that was set.

1 Samuel 26:16 In-Context

14 David cried to the people, and to Abner, the son of Ner, and said, Abner, whether thou wilt not answer? (Abner, wilt thou not answer me?) And Abner answered, and said, Who art thou, that criest, and dis-easest the king?

15 And David said to Abner, Whether thou art not a man (Art thou not a man), and what other man is like thee in Israel? why therefore hast thou not kept thy lord the king (safe)? For one man of the company entered, that he should slay thy lord the king;

16 this that thou hast done, is not good; the Lord liveth, for ye be sons of death, that kept not your lord, the christ of the Lord (this is not good, what thou hast done; as the Lord liveth, for ye be the sons of death, who kept not your lord safe, yea, the Lord's anointed). Now therefore see thou, where is the spear of the king, and where is the cup of water, that was at his head.

17 Forsooth Saul knew the voice of David, and said, Whether this voice is thine, my son David? And David said, My lord the king, it is my voice. (And Saul knew the voice of David, and said, Is this thy voice, David my son? And David said, My lord the king, it is my voice.)

18 And David said, For what cause pursueth my lord his servant? What have I done, either what evil is in mine hand?
