Read 1 Samuel 27:1 Using Other Translations
And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should speedily escape into the land of the Philistines; and Saul shall despair of me, to seek me any more in any coast of Israel: so shall I escape out of his hand.
Then David said in his heart, "Now I shall perish one day by the hand of Saul. There is nothing better for me than that I should escape to the land of the Philistines. Then Saul will despair of seeking me any longer within the borders of Israel, and I shall escape out of his hand."
But David kept thinking to himself, “Someday Saul is going to get me. The best thing I can do is escape to the Philistines. Then Saul will stop hunting for me in Israelite territory, and I will finally be safe.”
