| Geneva Study Bible And David said, What have I now done? Is there not a {i} cause? (i) For his father's sending was a just occasion, and also he felt himself inwardly moved by God's Spirit. Wesley's Notes 17:29 A cause - Of my thus speaking? Is this giant invincible? Is our God unable to oppose him, and subdue him? However David is not deterred from his undertaking, by the hard words of Eliab. They that undertake public services must not think it strange, if they be opposed by those from whom they had reason to expect assistance, but must humbly go on with their work, in the face, not only of their enemies threats, but of their friends slights, suspicions, and censures. Matthew Henry's Concise Commentary 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. |
