Kabbalah do Samuela I 21:14

Come and behold, When King David was saved from Achish, King of Gat, he said, "The angel of Hashem encamps..." For the Shechinah surrounded him and saved him from Achish, his people, and those who attacked him. As it is written, "וַיִּתְהוֹלֵל (Eng. 'feigned himself mad') in their hands" (I Samuel 21:14). He asks, Why is it written "Vayitholel" rather than 'וַיִּשְׁתַּגֵּעַ', as it is written, "you have brought this fellow to play the mad man (Heb. וַיִּשְׁתַּגֵּעַ) in my presence?" (I Sam. 21:16).
