(30) Went forth.--Probably to avenge the last raid of David (recounted in 1Samuel 18:27). Wordsworth, quoting from the Rabbis, suggests that they were emboldened to make this attack, supposing that their successful foe would, according to the Hebrew Law, claim exemption from warfare for a year after marriage (Deuteronomy 24:5).

Verse 30. - The princes of the Philistines went forth. See on ver. 5. This new war was the result of David's raid, but it only led to an increase of his fame and popularity. For he behaved himself more wisely. I.e. was more successful and skilful than any of Saul's other officers.

18:12-30 For a long time David was kept in continual apprehension of falling by the hand of Saul, yet he persevered in meek and respectful behaviour towards his persecutor. How uncommon is such prudence and discretion, especially under insults and provocations! Let us inquire if we imitate this part of the exemplary character before us. Are we behaving wisely in all our ways? Is there no sinful omission, no rashness of spirit, nothing wrong in our conduct? Opposition and perverseness in others, will not excuse wrong tempers in us, but should increase our care, and attention to the duties of our station. Consider Him that endured contradiction of sinners against himself, lest ye be weary and faint in your minds, Heb 12:3. If David magnified the honour of being son-in-law to king Saul, how should we magnify the honour of being sons to the King of kings!Then the princes of the Philistines went forth,.... Out of their cities in troops, to revenge and spoil the land of Israel, being enraged at their defeat when Goliath their champion was slain, and at the injury and dishonour done them by David very lately in slaying two hundred of them, and taking off their foreskins; and, as the Jews say (b), having heard of the marriage of David, and understanding the Israelites had a law, that a newly married man might not go to the war the first year, took this opportunity of invading and spoiling them; whereas David understood that law better than they, and knew it referred not to a voluntary war, but to that which was the command of God against the seven nations; and even in that case, as some think, it did not oblige such persons to remain at home, but left it to their choice to do as they pleased:

and it came to pass after they went forth; and were met and opposed by the Israelites, by the troops of Saul, under different commanders:

that David behaved himself more wisely than all the servants of Saul; showed himself to be more expert in the art of war, and formed designs with great wisdom and prudence, and which he as wisely executed, as well as with great courage and valour, to the annoyance and defeat of the enemy, and to the advantage, defence, and safety of the people of Israel; or he was more "prosperous" than they, as the Targum, and so others interpret it; he was more successful in his attacks on the Philistines, and in his skirmishes with them:

so that his name was much set by; he was in high esteem with the people; his name was "precious" (c) to them, as the word signifies; they made mention of it, as, Ben Gersom interprets it, with great honour and glory; so that Saul failed much, and was greatly disappointed in the scheme he had formed against him,
