20 And David riseth early in the morning, and leaveth the flock to a keeper, and lifteth up, and goeth, as Jesse commanded him, and he cometh in to the path, and to the force which is going out unto the rank, and they have shouted for battle; 21 and Israel and the Philistines set in array rank to meet rank. 22 And David letteth down the goods from off him on the hand of a keeper of the goods, and runneth into the rank, and cometh and asketh of his brethren of welfare. 23 And he is speaking with them, and lo, a man of the duellists is coming up, Goliath the Philistine 'is' his name, of Gath, out of the ranks of the Philistines, and he speaketh according to those words, and David heareth; 24 and all the men of Israel when they see the man flee from his presence, and are greatly afraid. 25 And the men of Israel say, 'Have ye seen this man who is coming up? for, to reproach Israel he is coming up, and it hath been—the man who smiteth him, the king doth enrich him with great riches, and his daughter he doth give to him, and his father's house doth make free in Israel.' 26 And David speaketh unto the men who are standing by him, saying, 'What is done to the man who smiteth this Philistine, and hath turned aside reproach from Israel? for who 'is' this uncircumcised Philistine that he hath reproached the ranks of the living God?'

Commentary on 1 Samuel 17:12-30
(Read 1 Samuel 17:12-30)
Jesse little thought of sending his son to the army at that critical juncture; but the wise God orders actions and affairs, so as to serve his designs. In times of general formality and lukewarmness, every degree of zeal which implies readiness to go further, or to venture more in the cause of God than others, will be blamed as pride and ambition, and by none more than by near relations, like Eliab, or negligent superiors. It was a trial of David's meekness, patience, and constancy. He had right and reason on his side, and did not render railing for railing; with a soft answer he turned away his brother's wrath. This conquest of his own passion was more honourable than that of Goliath. Those who undertake great and public services, must not 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.
