וַיָּ֤טֶל שָׁאוּל֙ אֶֽת־הַחֲנִ֔ית וַיֹּ֕אמֶר אַכֶּ֥ה בְדָוִ֖ד וּבַקִּ֑יר וַיִּסֹּ֥ב דָּוִ֛ד מִפָּנָ֖יו פַּעֲמָֽיִם׃
掃羅把矛擲出，說：«我要擊中大衛，把他連同牆壁一併擊穿。»大衛從他面前躲開了兩次。
Rashi
I will strike Dovid and the wall. I will strike one blow so, that the spear will pierce Dovid and the wall.2Shaul wanted to strike Dovid in a manner that it would appear that it was unintentional.
