Psalm 81:15BSB·traditional attribution

Those who hate the LORD would feign obedience, and their doom would last forever.

John Calvin Reformed @genevareformer

PSALM 81 This psalm consists of two parts. Whoever was its author, he exhorts the people to remember the unparalleled grace of God towards them, in delivering them by his outstretched arm, and choosing them to be a kingdom of priests, and a peculiar Church to himself; that thus they may be excited devoutly to honor their deliverer, both by celebrating his praises, and by leading a holy life.

The haters of the Lord should have submitted themselves unto him. Though the submission would have been false and flattering, yet the enemies of Israel would have been so humiliated that they would have hastened to make terms with the favoured tribes. Our enemies become abashed and cowardly when we, with resolution, walk carefully with the Lord.

Matthew Henry Presbyterian @wholebiblehenry

God, by the psalmist, here speaks to Israel, and in them to us, on whom the ends of the world are come. I. He demands their diligent and serious attention to what he was about to say (Psa 81:8): "Hear, O my people! and who should hear me if my people will not? I have heard and answered thee; now wilt thou hear me?
