psa 132:1The writer, perhaps Solomon (compare Psa 132:8-9), after relating David's pious zeal for God's service, pleads for the fulfilment of the promise (Sa2 7:16), which, providing for a perpetuation of David's kingdom, involved that of God's right worship and the establishment of the greater and spiritual kingdom of David's greater Son. Of Him and His kingdom both the temple and its worship, and the kings and kingdom of Judah, were types. The congruity of such a topic with the tenor of this series of Psalms is obvious. (Psa. 132:1-18)
This vow is not elsewhere recorded. It expresses, in strong language, David's intense desire to see the establishment of God's worship as well as of His kingdom.
remember David--literally, "remember for David," that is, all his troubles and anxieties on the matter.
psa 132:5habitation--literally, "dwellings," generally used to denote the sanctuary.

psa 132:7The purpose of engaging in God's worship is avowed.
psa 132:8The solemn entry of the ark, symbolical of God's presence and power, with the attending priests, into the sanctuary, is proclaimed in the words used by Solomon (Ch2 6:41).
psa 132:10For thy servant David's sake--that is, On account of the promise made to him.
turn . . . anointed--Repulse not him who, as David's descendant, pleads the promise to perpetuate his royal line. After reciting the promise, substantially from Sa2 7:12-16 (compare Act 2:30, &c.), an additional plea,
psa 132:13is made on the ground of God's choice of Zion (here used for Jerusalem) as His dwelling, inasmuch as the prosperity of the kingdom was connected with that of the Church (Psa 122:8-9).
psa 132:14That choice is expressed in God's words, "I will sit" or "dwell," or sit enthroned. The joy of the people springs from the blessings of His grace, conferred through the medium of the priesthood.
psa 132:17make the horn . . . to bud--enlarge his power.
a lamp--the figure of prosperity (Psa 18:10, Psa 18:28; Psa 89:17). With the confounding of his enemies is united his prosperity and the unceasing splendor of his crown.
