Still the ark is David's care as well as his joy. In this chapter we have, I. His consultation with Nathan about building a house for it; he signifies his purpose to do it (Sa2 7:1, Sa2 7:2) and Nathan approves his purpose (Sa2 7:3). II. His communion with God about it. 1. A gracious message God sent him about it, accepting his purpose, countermanding the performance, and promising him an entail of blessings upon his family (Sa2 7:4-17). 2. A very humble prayer which David offered up to God in return to that gracious message, thankfully accepting God's promises to him, and earnestly praying for the performance of them (Sa2 7:18-29). And, in both these, there is an eye to the Messiah and his kingdom.
