1 Samuel 19:24

Now, it seems to me that fortuitous circumstance also is sometimes the cause of prophesying, as is true in the present case of Caiaphas. He was high priest of that year [in which] Jesus was to die for the people that the whole nation might not perish. For although others were high priests … no one prophesies except the high priest of the year in which Jesus was to suffer.And it was fortuitous circumstance that caused the messengers of Saul to prophesy when they were sent to David, along with Saul himself.

The book of Kings [Samuel] gives us an example about prophecy. Saul was the persecutor of David. When he was persecuting him, he sent guards to drag him away to punishment, and those who were sent to bring David to be slain found him among the prophets; and Samuel was there too.… So he had fled to the place where besides Samuel, the most distinguished of all the prophets, there were also many other prophets. Pushing their way among them, while they were prophesying, came the emissaries of Saul, to drag him off, as I said, to death. The spirit of God leaped upon them and they began to prophesy, having come to lead a holy and just man of God to the execution block and snatch him away from among the prophets. They were suddenly filled with the spirit of God and turned into prophets. It's possible this happened because of their innocence; after all, they hadn't come of their own accord to arrest him but had been sent by their king. And perhaps they had indeed come to the place where David was but weren't going to do what Saul had told them to; perhaps they too were intending to stay there. Because such things even happen today. Sometimes a bailiff is sent by high authority to drag somebody out of the church; he dare not act against God, and in order not to face execution himself he stays there, in the place he was sent, to haul someone out of it. So you could say, pleasantly surprised and relieved, that these men suddenly became prophets because they were innocent; the very gift of prophecy bore witness to their innocence. They came because they were sent, but they weren't going to do what that bad man had told them to. Let us believe that about them.Others were sent; the Spirit of God leaped on them too, and they too began to prophesy. Let's count them too with the first lot as being quite innocent. […]

For all who do not love God are strangers, are antichrists. And though they come to the churches, they cannot be numbered among the children of God. That fountain of life does not belong to them. To have baptism is possible even for a bad person; to prophesy is possible even for a bad person. We find that king Saul prophesied: he was persecuting holy David, yet he was filled with the spirit of prophecy and began to prophesy.

He also stripped himself of his garments, etc. These are clearly the acts of a furious and insane person, to strip oneself, fall down vexed, and lie naked on the ground all day and night. Yet, even through the wrath of such a person, the …

From where the proverb emerged, "Is Saul also among the prophets?" The Jews of the Church have become a proverb, who, with a perverted mentality, make use of Holy Scriptures, which they do not believe or understand, while among the faithful attentive to sacred readings. …
