ולא נשא ב' במסורה הכא ואידך ולא נשא דוד מספרם. שהיה להם רכוש הרבה אין מספר: "ולא נשא" in both instances: "And David did not count their number, and their wealth was beyond measure."

["ולא נשא" literally means "and not counted" or "not enumerated". In the context of the passage, it is referring to the great wealth of David and his followers which was so vast that it could not be counted or enumerated]
