If Saul's wife Ahinoam was the same woman whom David also took to wife (as a claim to the throne), this would violate the character and motive of David to rely upon God's providence with regard to Saul and the throne. David was very popular with the people and was given opportunity to kill Saul (1 Sam 24) but would not hurt or take the life of the one whom God had anointed king (v. 10). Jezreel, the city from which Ahinoam comes, was also in northern Israel in Issachar, and a place of many natural fortresses - a good place for David's exile. Perhaps Ahinoam and David met while he was there?
