O Lord God of hosts - See the notes at Psalms 84:1. God is appealed to here as a God of power; as a God who is able to accomplish all his purposes, and to impart every needed blessing.
Hear my prayer - A prayer of the psalmist that he might also have a place among the servants of God in their worship, Psalms 84:2. To this earnestness of prayer he is excited by the view which he had of the blessedness of those who went with songs up to Zion. His soul longs to be among them; from the sight of them his prayer is the more fervent that he may partake of their blessedness and joy.
Give ear, O God of Jacob - With whom Jacob wrestled in prayer, and prevailed. Genesis 32:24-30. On the phrase, “give ear,” see the notes at Psalms 5:1.
