This enemy of his enemy-Israel’s King Saul-could be counted on as a friend. Achish would have heard of Saul’s war with David, so he probably felt secure in allowing him into the city.

This time, David did not have to feign insanity. David had been there before, and he deceived the city’s king, Achish, by pretending to be insane, thereby keeping the Philistines from killing him (21:10–15). We see in 1 Samuel 27:1–4 that David decided the best way to escape Saul was to flee to Philistine territory and take up residence in the city of Gath. It is easy enough to understand what is going on however, it is difficult to know how to evaluate it. Today’s passage certainly qualifies as one of the more difficult passages of Scripture. Some passages are more difficult to interpret than others even if no one can miss the gospel in the pages of the Bible. This doctrine of perspicuity also recognizes that not everything in Scripture is easy to understand. Advanced education can be helpful, but it is not required to know what God expects of us. Our doctrine of the perspicuity, or clarity, of Scripture tells us that the Bible is so clear on the basics of salvation that anyone of normal intelligence who carefully reads God’s Word can discern the essential gospel.
