Psalm 132 is one of the Psalms of Ascent, sung by the people of Israel when they traveled up to Jerusalem. I take it to be penned by Solomon, given that the language of this psalm is similar to Solomon’s prayer at the dedication of the temple (2 Chronicles 6:41). You have to keep in mind when reading the Psalms of Ascent that the saints of old sang them on the way up to Jerusalem, but you sing them having already trekked up to the heavenly Jerusalem (Hebrews 12:22). This can be a bit disorienting. And to make things even more interesting, they sang them going up to the holy city, but you sing them with the holy city coming down on your heads (Revelation 21:2–3).
