Królów II 3:15 Komentarz: Rashi & Metzudat David

Bring me a musician. Because of his anger, the Divine Presence departed from him.¹¹See Maseches Pesachim 66b. Alternatively, Elisha was unable to prophesy because he was mourning Eliyahu’s departure. The Divine Presence does not reside with people who are sad. It rests on prophets only when they experience joy in their fulfillment of a mitzvah. See Maseches Pesachim 117a.

Bring me a minstrel: To make me happy with his song, because of the anger Elisha had towards Yehoram, he did not receive prophecy, for prophecy is only received in happiness, and anger brings sadness

When (the minstrel) played: When the minstrel began to play, the spirit of prophecy came to him (Elisha)
