The effect of these victories must have been very striking. In the Song of the Bow, David had celebrated the public services of Saul, who had "clothed the daughters of Israel in scarlet, with other delights, who had put on ornaments of gold on their apparel"; but all that Saul had done for the kingdom was now thrown into the shade by the achievements of David. With all his bravery, Saul had never been able to subdue his enemies, far less to extend the limits of the kingdom. David accomplished both; and it is the secret of the difference that is expressed in the words, "The Lord gave victory to David whithersoever he went." It is one of the great lessons of the Old Testament that the godly man can and does perform his duty better than any other man, because the Lord is with him: that whether he be steward of a house, or keeper of a prison, or ruler of a kingdom, like Joseph; or a judge and lawgiver, like Moses; or a warrior, like Samson, or Gideon, or Jephthah; or a king, like David, or Jehoshaphat, or Josiah; or a prime minister, like Daniel, his godliness helps him to do his duty as no other man can do his. This is especially a prominent lesson in the book of Psalms; it is inscribed on its very portals; for the godly man, as the very first Psalm tells us, "shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither, and whatsoever he doeth shall prosper." In these warlike expeditions, King David foreshadowed the spiritual conquests of the Son of David, who went forth "conquering and to conquer," staggered for a moment, as in Gethsemane, by the rude shock of confederate enemies, but through prayer regaining his confidence in God, and triumphing in the hour and power of darkness. That noble effusion of fire and feeling, the sixty-eighth Psalm, seems to have been written in connection with these wars. The soul of the Psalmist is stirred to its depths; the majestic goings of Jehovah, recently witnessed by the nation, have roused his most earnest feelings, and he strains every nerve to produce a like feeling in the people. The recent exploits of the king are ranked with His doings when He marched before His people through the wilderness, and Mount Sinai shook before Him. Great delight is expressed in God's having taken up His abode on His holy hill, in the exaltation of His people in connection with that step, and likewise in looking forward to the future and anticipating the peaceful triumphs when "princes should come out of Egypt, and Ethiopia stretch forth her arms to God." Benevolent and missionary longings mingle with the emotions of the conqueror and the feelings of the patriot. "Sing unto the Lord, ye kingdoms of the earth; Oh, sing praises unto the Lord, To Him that rideth upon the heaven of heavens that are of old. Lo, He uttereth His voice, and that a mighty voice."
