Shmuel Alef 27:11-12

Orthodox Jewish Bible

¹¹ And Dovid saved neither ish nor isha alive, to bring [news] to Gat, saying, Lest they should inform on us, saying, So did Dovid, and so has been his mishpat (practice) all the yamim (days) he dwelleth in the sadeh of the Pelishtim (Philistines).

¹² And Achish believed Dovid, saying, He hath made his people Yisroel utterly to abhor him; therefore he shall be eved to me olam (forever).
