1st Samuel 29:8

5 Is not this David, of whom they answer in choruses, saying, Saul hath smitten among his thousands, and David among his myriads?`

6 And Achish calleth unto David, and saith unto him, `Jehovah liveth, surely thou [art] upright, and good in mine eyes is thy going out, and thy coming in, with me in the camp, for I have not found in thee evil from the day of thy coming in unto me till this day; and in the eyes of the princes thou art not good;

7 and now, turn back, and go in peace, and thou dost do no evil in the eyes of the princes of the Philistines.`

8 And David saith unto Achish, `But what have I done? and what hast thou found in thy servant from the day that I have been before thee till this day -- that I go not in and have fought against the enemies of my lord the king?`

9 And Achish answereth and saith unto David, `I have known that thou [art] good in mine eyes as a messenger of God; only, the princes of the Philistines have said, He doth not go up with us into battle;

10 and now, rise thou early in the morning, and the servants of thy lord who have come with thee, when ye have risen early in the morning, and have light, then go ye.`

11 And David riseth early, he and his men, to go in the morning, to turn back unto the land of the Philistines, and the Philistines have gone up to Jezreel.
