After this, it is said (v. 1), David did those great exploits. After the sweet communion he had had with God by the word and prayer, as mentioned in the foregoing chapter, he went on his work with extraordinary vigour and courage, conquering and to conquer. Thus Jacob, after his vision, lifted up his feet, Gen. xxix. 1.
We have taken a view of these victories before, and shall now only observe, 1. Those that have been long enemies to the Israel of God will be brought down at last. The Philistines had, for several generations, been vexatious to Israel, but now David subdued them, v. 1. Thus shall all opposing rule, principality, and power, be, at the end of time, put down by the Son of David, and the most inveterate enemies shall fall before him. 2. Such is the uncertainty of this world that frequently men lose their wealth and power when they think to confirm it. Hadarezer was smitten as he went to establish his dominion, v. 3. 3. A horse is a vain thing for safety, so David said (Ps. xxxiii. 17), and it seems he believed what he said, for he houghed the chariot-horses, v. 4. Being resolved not to trust to them (Ps. xx. 7), he would not use them. 4. The enemies of God's church are often made to ruin themselves by helping one another, v. 5. The Syrians of Damascus were smitten when they came to help Hadarezer. When hand thus joins in hand they shall not only not go unpunished, but thereby they shall be gathered as the sheaves into the floor, Mic. iv. 11, 12. 5. The wealth of the sinner sometimes proves to have been laid up for the just. The Syrians brought gifts, v. 6. Their shields of gold and their brass were brought to Jerusalem, v. 7, 8. As the tabernacle was built of the spoils of the Egyptians, so the temple of the spoils of other Gentile nations, a happy presage of the interest the Gentiles should have in the gospel church.
