Adam Clarke on 2 Samuel 23:11

A piece of ground full of lentiles - In 1Chr 11:13 it is a parcel of ground full of barley. There is probably a mistake of עדשים adashim, lentiles, for שעורים seorim, barley, or vice versa. Some think there were both lentiles and barley in the field, and that a marauding party of the Philistines came to destroy or carry them off, and these worthies defeated the whole, and saved the produce of the field. This is not unlikely.
