In Genesis chapter 20 Sailhamer views Abraham as a prophet who prays for and restores foreign people who wish for God’s restoration. In the incident with Abimelech, “Abraham’s words (vv. 11-13) serve to show that he had mistakenly judged the Philistines to be a wicked people, something which the actions of the Philistines proved false” (Sailhamer 1992, 175).
