Psalm 81
This psalm was probably composed for the Feast of Trumpets, on the first day of the seventh month, Lev. 23:24. Here are, (1.) Solemn exhortations to praise God for what he is to his people, and for what he hath done for them, ver. 1-7. (2.) Instructions concerning God's new-covenant grant of himself and his benefits to men; their ungrateful refusal thereof; and the misery they incur, and happiness they lose thereby, ver. 8-16.
While I sing, let my soul consider what God is to, hath done for, and given to men to me: and let all my inward powers steadfastly believe his declarations, and eagerly embrace his offers. Let my heart be filled with grief, that ever I refused to hear my own gracious God speaking from heaven, and offering to me all the unsearchable riches of Christ.
