This Psalm seems to have been made for the use of the church in solemn feasts; particularly either upon every first day of the month, or upon the first day of the seventh mouth, which was celebrated with more solemn blast of trumpets, Lev_23:24Num_29:1; because that month was more sacred than others by reason of the concurrence of divers religious solemnities in it.
Gittith; of which title See Poole "Psa_8:1".
An exhortation to a solemn praising of God, Psa_81:1-3; which he requireth for his manifold mercies and deliverances, Psa_81:4-7; and, exhorting to obedience, and the worshipping of him the true God, Psa_81:8-10, complaineth of their disobedience, which tended to their own hurt and affliction, Psa_81:11-16.
Our strength; who is all our refuge and safeguard against all our enemies.
