1 Chronicles 10:13-14

Young's Literal Translation

¹³ And Saul dieth because of his trespass that he trespassed against Jehovah, against the word of Jehovah that he kept not, and also for asking at a familiar spirit -- to inquire, --

¹⁴ and he inquired not at Jehovah, and He putteth him to death, and turneth round the kingdom to David son of Jesse.
