“So David went, he and the six hundred men that were with him, and came to the brook Besor, where those that were left behind stayed.”
King James Version (KJV)
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.
30:8 He answered - Before, God answered more slowly and gradually, chap.#23:11|,12, but now he answers speedily, and fully at once, because the business required haste. So gracious is our God, that he considers even the degree of our necessities, and accommodates himself to them.
30:10 Four hundred - A small number for such an attempt: but David was strong in faith, giving God the glory of his power and faithfulness.
