132:11-12 God promised David that He would raise up a dynasty of David's descendents that would follow him on Israel's throne (2 Sam. 7:12-16). If they were faithful to the Lord, He would give them an unbroken succession. Of course this did not take place because David's descendents did not all follow God faithfully. Nevertheless God preserved David's dynasty.
132:13-16 God also promised to make Zion His special habitation (2 Chron. 6:6; 34-39). He said He would bless it by providing food for the poor, salvation for the priests (cf. v. 9), and joy for the godly.
132:17-18 The horn of David that God promised would spring forth refers to a ruler that He would raise up from David's descendents (cf. Dan. 7:24; Luke 1:69). The lamp is a figure for a leader (cf. 2 Sam. 21:17; 1 Kings 11:36). It refers to the same person God said He would prepare for His anointed, David. In other words, God promised to raise up one of David's descendents who would defeat His enemies. This promise found partial fulfillment in some of David's successors who followed him on the throne of Israel, but Messiah will fulfill it ultimately.
This royal psalm should encourage God's people to believe that He will fulfill His promises, specifically the promises regarding David's descendent and capital.
