1 Samuel 19:20

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.

Ver. 20. And Saul sent messengers to take David.] Contra gentes, as they say, and whosoever should say nay to it: not sparing the prophets, but if they opposed, putting them all to the sword, as he afterwards did the priests of Nob. All malice is bloody and barbarous so far as it dare show itself.

And when they saw the company of the prophets prophesying.] That is, Praising God, praying, and preaching, to the no small comfort of distressed David, who might well say, "In the multitude of my perplexed thoughts within me, thy comforts have refreshed my soul." Psa 94:19

And Samuel standing as appointed over them.] As their president. For though Samuel had given over the public government of the commonwealth, yet he would not live to himself, as did Sulla after that he had resigned the dictatorship: but as Cato - after that he had ridden in triumph, and so had a writ of case given him - exercised himself still for the good of the public, -

“ Ut qui toti genitum se credidit orbi. ”

So Samuel hated to be idle or unprofitable: and therefore exercised himself in his prophetical office still. So Moses when he may not in Egypt, will be doing justice in Midian: in Egypt he delivered the oppressed Israelite, in Midian the wronged daughters of Jethro. I had rather be sick in my bed than idle, saith Seneca.

And they also prophesied.] They put off their military clothes, and acted the prophets in habit and gesture, forgetting the business they came about. Disce hic quantum valeat bonorum societas, saith A. Lapide. See here the efficacy of good company: surely as the loadstone draweth iron, so spiritual exercises are able to affect the hearts and affections of others.
