1 Samuel 26:16

This thing [is] not good that thou hast done. [As] the LORD liveth, ye [are] worthy to die, because ye have not kept your master, the LORD'S anointed. And now see where the king's spear [is], and the cruse of water that [was] at his bolster.

Ver. 16. Ye are worthy to die,] sc., Ex iure Gentium, because ye keep no better a watch. Epaminondas walking the round, slew a watchman whom he found sleeping; and defended the fact by saying, Talem reliqui, qualem inveni, I left him no otherwise than I found him.

And now see where the king's spear is.] Ecce signum, lo here an ocular demonstration of thy blameworthiness, but of mine integrity and innocence.
