1 Samuel 19:19-24

(19) And it was told Saul, saying, Behold, David is at Naioth in Ramah. (20) And Saul sent messengers to take David: and when they saw the company of the prophets prophesying, and Samuel standing as appointed over them, the Spirit of God was upon the messengers of Saul, and they also prophesied. (21) And when it was told Saul, he sent other messengers, and they prophesied likewise. And Saul sent messengers again the third time, and they prophesied also. (22) Then went he also to Ramah, and came to a great well that is in Sechu: and he asked and said, Where are Samuel and David? And one said, Behold, they be at Naioth in Ramah. (23) And he went thither to Naioth in Ramah: and the Spirit of God was upon him also, and he went on, and prophesied, until he came to Naioth in Ramah. (24) And he stripped off his clothes also, and prophesied before Samuel in like manner, and lay down naked all that day and all that night. Wherefore they say, Is Saul also among the prophets?

Those effects wrought upon the mind of Saul and messengers, seem to confirm what was said before, that certain impressions were wrought upon the minds of men according to the pleasure of the Lord, from the exercises of the prophets in their schools. In this instance, at least, it was made the means, in the Lord's hands, to deliver David from the power of Saul. The Lord hath a thousand methods, in the stores of omnipotency, to answer the purposes of his grace. And he knoweth how to deliver the godly out of temptation. And let not the Reader be surprized that the Lord should cause the same influence to work upon the mind of Saul. In all ages, bad men have been sometimes made the unwilling instruments of his pleasure. We read of New Testament Prophets, who shall be commissioned to much good to others, but in the end be found unrenewed in themselves, and rejected of God. Matthew 7:22-23 .
