1 Samuel 21:10-12

New Catholic Bible

¹⁰ That day David rose up and fled because he was afraid of Saul. He went to Achish, the king of Gath. ¹¹ The servants of Achish said to him, “Is this not David, the king of the land? Is he not the one they sing about as they dance, ‘Saul has killed his thousands, David has killed his ten thousands.’ ”

¹² David Pretends Insanity. David took these words to heart, and he was terrified of Achish, the king of Gath.
