SEV Biblia, Chapter 17:19
Y Saúl y ellos y todos los de Israel, estaban en el valle del Alcornoque, peleando contra los filisteos.
Clarke's Bible Commentary - 1 Samuel 17:19
Verse 19. Fighting with the Philistines.] See at the end of the chapter.
John Gill's Bible Commentary
Ver. 19. Now Saul, and they , etc.] That is, the sons of Jesse, and brethren of David: and all the men of Israel ; the soldiers in the army: were in the valley Elah ; or “by” it, near unto it; for they were set in array on the mountain on the side of it: fighting with the Philistines ; not actually engaged in battle, but drawn up for it; prepared and in readiness to engage whenever it was necessary, or they were obliged to it; and perhaps there might be now and then some skirmishes in the outer parts of the camp.
Matthew Henry Commentary
Verses 12-30 - Jesse little thought of sending his son to the army at that critica juncture; but the wise God orders actions and affairs, so as to serv his designs. In times of general formality and lukewarmness, ever degree of zeal which implies readiness to go further, or to ventur more in the cause of God than others, will be blamed as pride an ambition, and by none more than by near relations, like Eliab, or negligent superiors. It was a trial of David's meekness, patience, an constancy. He had right and reason on his side, and did not rende railing for railing; with a soft answer he turned away his brother' wrath. This conquest of his own passion was more honourable than tha of Goliath. Those who undertake great and public services, must no think it strange if they are spoken ill of, and opposed by those from whom they expect support and assistance. They must humbly go on with their work, in the face not only of enemies' threats, but of friends slights and suspicions.
