Chasidut su I Samuele 19:78

Thus God’s spirit had fallen upon Saul as he approached (but had not even yet arrived) at Samuel’s city—‘and he walked on, prophesying.”²²³I Samuel 19:23. JPS has ‘speaking in ecstasy.’ Samuel had sanctified the world, and when Saul drew close to his city, there was so much holiness and prophecy lying there that he too began to prophesize. Through the great sanctification that the prophets drew down onto the world and Israel, the Blessed One dwells and joins with Israel.

We see something similar regarding the other prophets. Whether or not they had prophecies, portends, or chastisement to give over to Israel at a given time, the prophet and his disciples gathered together nonetheless to serve God with a supernal, prophetic avodah. The prophet revealed the light which appeared on him, and they in turn were illuminated by his light and also spread additional light upon him. As the verse states [I Samuel 19:20], “They saw a band of prophets speaking in prophecy, with Samuel sanding by as their leader;” and the Targum [Jonathan] translates, “...a band of prophets were praising [meshabkhin].” This indicates that the prophet gave onto them all of his light from Above, and even the servants of Saul prophesied when they came under his holy shade. Yet, how could this be possible, that the prophet would give over the majority of his light to people who spend their whole year in vineyards and olive-groves, only coming to him occasionally? Can one build a prophet from this, with all his loftiness and influence, to people preoccupied with this world and its needs, even be they servants of God?! If this is what the prophet and his disciples needed, they would be established by him continuously, praising and serving His name with him. Some of them merited thereafter to become one of the forty-eight prophets, and the others were at the least prophets for their own generations, as we said above. They prepared their generation, purifying and elevating it to be able to receive actual effluence of holiness, souls, sefirot, and the spirit of God which He sent him.
