And it came to pass that night,.... The same night following the day in which David and Nathan had had the above conversation, that neither of them might continue long in their error and mistake, and especially lest David, in his great zeal and warm affection, should take an hasty and improper step:
that the word of the Lord came unto Nathan; the word of prophecy, as the Targum; before he was not under a prophetic influence, but spoke in his own words, and had not the word of God; but now it came to him:
saying; as follows.
Blessings are promised to the family and posterity of David. These promises relate to Solomon, David's immediate successor, and the royal line of Judah. But they also relate to Christ, who is often called David and the Son of David. To him God gave all power in heaven and earth, with authority to execute judgment. He was to build the gospel temple, a house for God's name; the spiritual temple of true believers, to be a habitation of God through the Spirit. The establishing of his house, his throne, and his kingdom for ever, can be applied to no other than to Christ and his kingdom: David's house and kingdom long since came to an end. The committing iniquity cannot be applied to the Messiah himself, but to his spiritual seed; true believers have infirmities, for which they must expect to be corrected, though they are not cast off.
GOD APPOINTS HIS SUCCESSOR TO BUILD IT. (2-Samuel 7:4-17)
it came to pass that night, that the word of the Lord came unto Nathan--The command was given to the prophet on the night immediately following; that is, before David could either take any measures or incur any expenses.
The revelation and promise of God. - 2-Samuel 7:4. "That night," i.e., the night succeeding the day on which Nathan had talked with the king concerning the building of the temple, the Lord made known His decree to the prophet, with instructions to communicate it to the king. וגו האתּה, "Shouldest thou build me a house for me to dwell in?" The question involves a negative reply, and consequently in the Chronicles we find "thou shalt not."
The word of the Lord came - Because David's mistake was pious, and from an honest mind, God would not suffer him to lie long in it.
