Shmuel Alef 19:9-10

And there was a ruach HASHEM ra'ah upon Sha'ul, as he sat in his Bais with his khanit (spear) in his yad; while Dovid menaggen (was playing music) with his yad. And Sha'ul sought to pin Dovid to the wall with the khanit; but he slipped away out of Sha'ulʼs presence, and he drove the khanit into the wall; and Dovid fled, and escaped that lailah.
