Thematic Bible: David takes refuge at

David arose, and fled that day for fear of Saul, and went to Achish the king of Gath. The servants of Achish said to him, "Isn't this David the king of the land? Did they not sing one to another about him in dances, saying, 'Saul has slain his thousands, David his ten thousands?'" David laid up these words in his heart, and was very afraid of Achish the king of Gath. read more.
He changed his behavior before them, and pretended to be mad in their hands, and scrabbled on the doors of the gate, and let his spittle fall down on his beard. Then Achish said to his servants, "Look, you see the man is mad. Why then have you brought him to me? Do I lack madmen, that you have brought this fellow to play the madman in my presence? Shall this fellow come into my house?"

David arose, and passed over, he and the six hundred men who were with him, to Achish the son of Maoch, king of Gath. David lived with Achish at Gath, he and his men, every man with his household, even David with his two wives, Ahinoam the Jezreelitess, and Abigail the Carmelitess, Nabal's wife. It was told Saul that David was fled to Gath: and he sought no more again for him. read more.
David said to Achish, "If now I have found favor in your eyes, let them give me a place in one of the cities in the country, that I may dwell there. For why should your servant dwell in the royal city with you?" Then Achish gave him Ziklag that day: why Ziklag pertains to the kings of Judah to this day. The number of the days that David lived in the country of the Philistines was a full year and four months.
