David said to Achish, If now I have found favor in your eyes, let them give me a place in one of the cities in the country, that I may dwell there: for why should your servant dwell in the royal city with you?
"Ziklag has belonged to the kings of Judah to this day"  (1 Samuel 27:6).  This writer believes that such expressions as this are in all probability interpolations due to some later copyist adding the words in the margin and which eventually found their way into the text.  Note that this expression is no part whatever of the narrative.  The use which most scholars make of an expression such as this is that of making it a device for late-dating the Biblical book where it is found.  To this writer, it seems very suspicious that critical scholars such as H. P. Smith who could always find anywhere from two or three to thirty or forty `interpolated verses' in a single chapter, always takes a comment like that at the head of this paragraph as the gospel truth and positive evidence of a late date. Such maneuvers are absolutely unbelievable.
