English Standard Version Anglicised

¹³ So he changed his behaviour before them and pretended to be insane in their hands and made marks on the doors of the gate and let his spittle run down his beard. ¹⁴ Then Achish said to his servants, “Behold, you see the man is mad. Why then have you brought him to me? ¹⁵ Do I lack madmen, that you have brought this fellow to behave as a madman in my presence? Shall this fellow come into my house?”
