Abiathar had continued to abide with David, ever since he joined him at Keilah 1 Samuel 23:6. On inquiry of the Lord by the ephod, see Judges 1:1 note. The answers were evidently given by the Word of the Lord in the mouth of the high priest (compare John 11:51).

Bring me hither the ephod - It seems as if David had put on the ephod, and inquired of the Lord for himself; but it is more likely that he caused Abiathar to do it.

And David said to Abiathar the priest, Ahimelech's son,.... The son of Ahimelech, who was slain at Nob by the order of Saul, 1 Samuel 22:19; and Abiathar his son, who fled to David with the ephod, on the death of his father, 1 Samuel 22:20, was now high priest in his room; and who it seems was with David when he went with Achish, and returned with him; for had he been left at Ziklag, he and his ephod, in all probability, had been carried off by the Amalekites, unless we can suppose him under the protection of a special providence: it is much David had not inquired of the Lord by him about his going with Achish; perhaps the present disaster brought to mind that neglect, and made him the more diligent now:

I pray thee, bring me hither the ephod; not to put it on himself, but that the high priest might put it on, and inquire by it before him of the Lord:

and Abiathar brought thither the ephod to David; for the sake of David, that inquiry might be made before him of the Lord by Urim and Thummim.

And David said to Abiathar the priest, Ahimelech's son, I pray thee, bring me hither the ephod. And Abiathar brought thither the ephod to David.

30:7 The ephod - And put it upon thyself, that thou mayst enquire of God according to his ordinance, David was sensible of his former error in neglecting to ask counsel of God by the ephod, when he came to Achish, and when he went out with Achish to the Battle; and his necessity now brings him to his duty, and his duty meets with success.

30:7-15 If in all our ways, even when, as in this case, there can be no doubt they are just, we acknowledge God, we may expect that he will direct our steps, as he did those of David. David, in tenderness to his men, would by no means urge them beyond their strength. The Son of David thus considers the frames of his followers, who are not all alike strong and vigorous in their spiritual pursuits and conflicts; but, where we are weak, there he is kind; nay more, there he is strong, 2Co 12:9,10. A poor Egyptian lad, scarcely alive, is made the means of a great deal of good to David. Justly did Providence make this poor servant, who was basely used by his master, an instrument in the destruction of the Amalekites; for God hears the cry of the oppressed. Those are unworthy the name of true Israelites, who shut up their compassion from persons in distress. We should neither do an injury nor deny a kindness to any man; some time or other it may be in the power of the lowest to return a kindness or an injury.
