But the main lesson of the prayer is that God's promise should ever be the basis and measure of prayer. The mould into which our petitions should run is, 'Do as Thou hast said.' Because God's promise had come to David, 'therefore hath Thy servant found in his heart to pray this prayer unto Thee.' There is no presumption in taking God at His word. True prayer catches up the promises that have fallen from heaven, and sends them back again, as feathers to the arrows of its petitions. Nor does the promise make the prayer needless. We know that 'if we ask anything according to His will, He heareth us'; and we know that we shall not receive the promised blessings, which are according to His will, unless we do ask. Let us seek to stretch our desires to the width of God's promises, and to confine our wishes within their bounds.
'And David said, is there yet any that is left of the house of Saul, that I may shew him kindness for Jonathan's sake? 2. And there was of the house of Saul a servant whose name was Ziba. And when they had called him unto David, the king said unto him, Art thou Ziba? And he said, Thy servant is he. 3. And the king said, Is there not yet any of the house of Saul, that I may shew the kindness of God unto him? And Ziba said unto the king, Jonathan hath yet a son, which is lame on his feet. 4. And the king said unto him, Where is he? And Ziba said unto the king, Behold, he is in the house of Machir, the son of Ammiel, in Lo-debar. 5. Then king David sent, and fetched him out of the house of Machir, the son of Ammiel, from Lo-debar., 6. Now when Mephibosheth, the son of Jonathan, the son of Saul, was come unto David, he fell on his face, and did reverence. And David said, Mephibosheth. And he answered, Behold thy servant! 7. And David said unto him. Fear not; for I will surely shew then kindness for Jonathan thy father's sake, and will restore thee all the land of Saul thy father: and thou shalt eat bread at my table continually. 8. And he bowed himself, and said, What is thy servant, that thou shouldest look upon such a dead dog as I am? 9. Then the king called to Ziba, Saul's servant, and said unto him, I hare given unto thy master's son all that pertained to Saul and to all his house. 10. Thou therefore, and thy sons, and thy servants, shall till the land for him, and thou shalt bring in the fruits, that thy master's son may have food to eat: but Mephibosheth thy master's son shall eat bread alway at my table. Now Ziba had fifteen sons and twenty servants. 11. Then said Ziba unto the king, According to all that my lord the king hath commanded his servant, so shall thy servant do. As for Mephibosheth, said the king, he shall eat at my table, as one of the king's sons. 12. And Mephibosheth had a young son, whose name was Micha: and all that dwelt in the house of Ziba were servants unto Mephibosheth. 13. So Mephibosheth dwelt in Jerusalem: for he did eat continually at the king's table; and was lame on both his feet.'--2 SAMUEL ix.1-13.
This charming idyl of faithful love to a dead friend and generous kindness comes in amid stories of battle like a green oasis in a wilderness of wild rocks and sand. The natural sweetness and chivalry of David's disposition, which fascinated all who had to do with him, comes beautifully out in it, and it may well stand as an object lesson of the great Christian duty of practical mercifulness.
I. So regarded, the narrative brings out first the motives of true kindliness. Saul and three of his four sons had fallen on the fatal field of Gilboa; the fourth, the weak Ishbosheth, had been murdered after his abortive attempt at setting up a rival kingdom had come to nothing. There were only left Saul's daughters and some sons by a concubine. So low had the proud house sunk, while David was consolidating his kingdom, and gaining victory wherever he went.
