An exhortation to the people to praise God for his benefits, Psa 81:1-7; and to attend to what he had prescribed, Psa 81:8-10; their disobedience lamented, Psa 81:11; the miseries brought on themselves by their transgressions, Psa 81:12-16.
The title is the same as to Psa 8:1-9 (note), which see. There are various opinions concerning the occasion and time of this Psalm: but it is pretty generally agreed that it was either written for or used at the celebration of the Feast of Trumpets, (see on Lev 23:24 (note)), which was held on the first day of the month Tisrl, which was the beginning of the Jewish year; and on that day it is still used in the Jewish worship. According to Jewish tradition, credited by many learned Christians, the world was created in Tisri, which answers to our September. The Psalm may have been used in celebrating the Feast of Trumpets on the first day of Tisri, the Feast of Tabernacles on the fifteenth of the same month, the creation of the world, the Feasts of the New Moons, and the deliverance of the Israelites from Egypt; to all which circumstances it appears to refer.
Verse 1
Sing aloud unto God our strength - There is much meaning here: as God is our strength, let that strength be devoted to his service; therefore, sing aloud! This is principally addressed to the priests and Levites.
