The removal of the ark to Jerusalem was but the first step in a process which was intended to end in the erection of a permanent Temple. The time for the next step appeared to David to have come when he had no longer to fight for his throne. Rest from enemies should lead to larger work for God, else repose will be our worst enemy, and peace will degenerate into self-indulgent sloth. A devout heart will not be content with personal comfort and dwelling in a house of cedar, while the ark has but a tent for its abode. There should be a proportion between expenditure on self and on religious objects. How many professing Christians might go to school to David! Luxury at home and niggardliness in God's work make an ugly pair, but, alas! a common one.
Nathan approved, as was natural. But he knew the difference between his own thoughts and 'the word of the Lord' that came to him, and, like a true man, he went in the morning and contradicted, by God's authority, his own precipitate sanction of the king's proposal. Clearly, divine communications were unmistakably distinguishable from the recipient's own thoughts.
The divine message first negatives the intention to build a house. In 1 Chronicles a positive prohibition takes the place of the question in verse 5, but that is only a difference of form, for the question implies a negative answer. From David's last words (1 Chron. xxviii. 3) we learn that a reason for the prohibition was 'because thou art a man of war, and hast shed blood.' His wars were necessary, and tended to establish the kingdom, but their existence showed that the time for building the Temple had not come, and there was a certain incongruity in a warrior king rearing a house for the God whose kingdom was in its essence peace.
The prohibition rests on a deep insight into the nature of Jehovah's reign, and draws a broad distinction between His worship and the surrounding paganism. But the reason given in the text is very remarkable. God did not desire a permanent Temple. If we may so say, He preferred the less solid Tabernacle, as corresponding better to the simplicity and spirituality of His worship. A gorgeous stone Temple might easily become the sepulchre, rather than the shrine, of true devotion. The movable tent answered to the temporary character of the 'dispensation.' The more fixed and elaborate the externals of worship, the more danger of the spirit being stifled by them. The Old Testament worship was necessarily ceremonial, but here is a caveat against the stiffening of ceremonial into stereotyped formalism.
The prohibition was accompanied by gracious and far-reaching promises, designed to assure David of God's approbation of his motive, and to open up to him the vision of the future and the wonders that should be. We need say little about the retrospective part of the message (verses 8, 9 a). God had been the agent in all David's past, had lifted him from the quiet following of his sheep, had given him rule, which was but a delegated authority. Israel was 'My people,' and therefore he was but an instrument in God's hand, and was not to govern by his own fancies or for his own advantage.
Every devout man's life is the realisation of a plan of God's, and we sin against ourselves as well as Him if we do not often let thankful thoughts retrace all the way by which the Lord our God has led us.
With verse 9 b the prophecy turns to the future. David personally is promised the continuance of God's help; then a permanent, peaceful possession of the land is promised to the nation, and finally the perpetuity of the kingdom in the Davidic line is promised. The prophecy as to the nation, like all such prophecies, is contingent on national obedience. The future of the kingdom will stand in blessed contrast with the wild times of the Judges, if—and only if—Israel behaves as 'My people' should.
But the main point of the prophecy is the promise to David's 'seed.' In form it attaches itself very significantly to David's intention to build a house for Jehovah. That would invert the true order, for Jehovah was about to build a house, that is, a permanent posterity, for David. God must first give before man can requite. All our relations to Him begin with His free mercy to us. And our building for Him should ever be the result of His building for us, and will, in some humble way, resemble the divine beneficence by which it has been quickened into action. The very foundation principles of Christian service are expressed here, in guise fitted to the then epoch of revelation.
But the relation of the two things, God's building and Solomon's, is not exhausted by such considerations. The consolidation of the monarchy in David's family was an essential preliminary to the rearing of the Temple. That work needed tranquil times, abundant resources, leisure, and assured dominion. So the prophet goes on to promise that David shall be succeeded by his 'seed,' who shall build the Temple.
Further, three great promises are given in reference to David's seed,—a perpetual kingdom, a personal relation of sonship to Jehovah, and paternal chastisement, if necessary, but no such departure of Jehovah's mercy as had darkened the close of Saul's sad reign. Then, finally, the assurance is reiterated of the perpetuity of David's house and throne. The remarkable expression in verse 16, 'established before thee' (that is, David), if it is the true reading, suggests a hint of the life after death, and conceives of the long-dead king as in some manner cognisant of the fortunes of his descendants. But the Septuagint reads 'before Me,' and that reading is confirmed by verses 26 and 29, and by Psalm lxxxix.36 b.
