Psalms 132:9-10

The Israelites also called on God to establish a righteous group of priests among them. and to enable the godly in Israel to rejoice because of His blessings. They asked God to remember His promises to David, His anointed king. In view of these requests, this psalm may date from the return from exile (cf. Psalms 132:16; Zechariah 3:1-7).
