A battle - at Gob - Instead of Gob, several editions, and about forty of Kennicott's and De Rossi's MSS., have Nob; but Gezer is the name in the parallel place, 1 Chronicles 20:4.
A battle in Gob - In the parallel passage (marginal reference), “Gezer” is named as the field of this battle. However, Gath is named 2 Samuel 21:20, 2 Samuel 21:22 in a way to make it probable that Gath was the scene of all the battles. The Septuagint in this verse has “Gath.”
