(20) He came to the trench.--Literally, to the wagon rampart; a circle of wagons formed a rude fortification about the camp of Israel. There--that is, within the fortified enclosure--he left (1Samuel 17:22) his baggage, the ten cheeses, &c, and hastened to the "front," where he knew his brethren and the men of Judah would be posted. (See Numbers 10:14.)

Verses 20-22. - He came to the trench. More probably the barricade, or outer circle of defence for their camp, made of their wagons (see on ch. 10:22). Strictly the word means a wagon track, but the primary meaning of the verb is to be round. This was the shape of camps in old time, and they were protected against surprise by having the wagons and baggage placed round them. The word occurs again in 1 Samuel 26:5, 7. The latter part of the verse is literally, "And he came to the circle of the wagons, and to the host that was going forth to the array; and they shouted for the battle." If the article be omitted before "going forth," for which there is some authority, the rendering of the A.V. would be right. David left his carriage. I.e. that which he was carrying. The word is rendered stuff in 1 Samuel 10:22; 1 Samuel 25:13; 1 Samuel 30:24. Literally the word means utensils, and so whatever he had with him for any purpose (comp. Acts 21:15). Ran into the army. Literally, "to the array," "to the ranks," the place where the troops were drawn up (see ver. 10).

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.And David rose up early in the morning,.... Being very ready and eager to obey his father's orders, and visit his brethren:

and left the sheep with a keeper; which showed his care and faithfulness in the discharge of his office; he was not unmindful of his father's sheep, any more than of his commands:

and took; the ephah of parched corn, the ten loaves, and the ten cheeses:

and went, as Jesse had commanded him; went and carried them to the camp, according to his orders:

and he came to the trench; foss or ditch, which was cast up all around the army, partly to prevent the enemy falling on them before, and partly to prevent deserters from them behind; or the word signifying a wagon or carriage, which is here used, this might be a fence around the camp made of wagons fastened to each other; though it may only signify, the camp itself, which lay in a circular form, with proper guards about it to watch the enemy. Now David came up to it just

as the host was going forth to the fight; preparing and getting every thing ready to the battle, and in motion, and upon the march to meet the enemy:

and shouted for the battle; which was usually done when about to make the onset, to animate the soldiers, and strike the greater terror into the enemy; and this noise was sometimes made with the voice in a hideous and howling way, and was called "barritus" (a) by the Romans; with the Trojans it was like the noise of cranes in the air (b); it was also attended with the clashing of shields and spears (c); with the Persians, it was a rough, boisterous, and confused noise (d).
