He had removed him; God had taken Saul away by death; for he would not suffer David to hasten it. After mine own heart; favoured or beloved by me, and obedient to me; my servant, as God speaks of him, Psalms 89:20. Which shall fulfil all my will; and here, that he should fulfil all God's will, to wit, in governing his people; for he hath a testimonial upon record in God's word, Psalms 78:72. He that is according to God's heart, fulfils all the will of God, and does nothing by partiality; but if it be God's will either for him to do or to suffer any thing, he is ready to set his fiat to it; as he daily prays (understandingly) that the will of the Lord may be done.
