Psalms 99:5

Exalt ye the Lord our God,.... Christ, who is Lord of all, and Immanuel, God with us, God in our nature, our Lord and our God; exalt him in his person, as God over all, blessed for ever; in his offices of Prophet, Priest, and King, by hearkening to his word, by trusting in his blood, righteousness, and sacrifice, and by submitting to his ordinances, and obeying his commands; exalt him in heart, thought, and affection, thinking highly of him, and affectionately loving him; exalt and extol him in words, speak of his love and loveliness, and of the great things he has done; exalt him in private and in public, in the family and in the house of God; make mention of him everywhere, that his name be exalted:

and worship at his footstool; worship him who is the object of the adoration of angels, and ought to be of men; worship him privately and publicly, internally and externally, in spirit and in truth; at his footstool, on earth, he being on his throne in heaven; see Isaiah 65:1 or else the ark is meant, which is so called, 1 Chronicles 28:2, and this being a type of the human nature of Christ, that may be meant here; and which, though not the object of worship, nor is it said, worship his footstool, but at it; yet, in worshipping Christ, respect is to be had unto him, as in our nature, in which he has done such great things for us: the Targum is,

"worship in or at the house of his sanctuary;''

so Kimchi interprets it of the sanctuary, which agrees with Psalms 99:9,

for he is holy: essentially holy, glorious in holiness as a divine Person, and therefore to be worshipped: or "it is holy"; the footstool, the ark, the human nature of Christ, in which the Godhead dwells bodily.
