When Shaul would scold his enemies e.g. the Plishtim, he would shout at them for “defying Israel” (as his men did in Shmuel 1:17:25), but David would shout at them for "defying God" (ibid 26).
I heard this in the name of Rav Kook.
Is there any discussion (especially in some sort of halachic sense) or criticism of Shaul for acting inappropriately by not mentioning Hashem? Other than Rav Kook
