Genesis 31:7

Changed my wages. “Ten” may not have been meant literally. It was used, perhaps, simply as a round number to indicate very frequent change, much as we would say “a dozen times” (cf. Dan. 1:20). Laban apparently made repeated attempts to limit the original agreement by changing its provisions. That Jacob passed over in silence his own stratagem and attributed to God’s blessing all that he secured by craft implies consciousness that the means employed were not completely honest.
