Saul sent messengers to take David: and when they saw the company of the prophets prophesying, and Samuel standing as head over them, the Spirit of God came on the messengers of Saul, and they also prophesied.
the Spirit of the Lord was upon the messengers of Saul, and they also prophesied: or praised, as the Targum; sung hymns and songs of praise as the prophets did, and were so taken up with these religious exercises, that they forgot, or were inattentive to the business they were sent to do. Ben Gersom thinks they foretold things to come, and so Abarbinel; and particularly that they prophesied that David should rule over all Israel, and that God would not suffer Saul to slay him; and so were indifferent to, and negligent of doing the errand they were sent on, yea, purposely avoided it.
