1 Samuel 22:17 YLT

[17] And the king saith to runners, those standing by him, `Turn round, and put to death the priests of Jehovah, because their hand also [is] with David, and because they have known that he is fleeing, and have not uncovered mine ear;' and the servants of the king have not been willing to put forth their hand to come against the priests of Jehovah.
