Psalms 99:5 - Joseph Benson’s Commentary on the Old and New Testaments

Exalt ye the Lord Give him the glory of the good government you are under, as it is now established. And worship at his footstool That is, at his ark, which was the footstool to the mercy-seat, between the cherubim. Or we must cast ourselves down upon the pavement of his courts; and good reason we have to be thus reverent, for he is holy, and his holiness should strike an awe upon us, as it doth on the angels themselves, Isaiah 6:2-3. Observe, reader, that God is to be worshipped and glorified, is the one inference always drawn from every position of David. And surely the greater the public mercies are in which we have a share, the more we are obliged to bear a part in the public homage paid to God. The setting up of the kingdom of Christ, especially, ought to be matter of our praise. Observe further, when we draw nigh to God to worship him, our hearts ought to be filled with high thoughts of him, and we ought to exalt him in our souls. And the more we abase ourselves, and the more prostrate we are before God, the more we exalt him.
