[Psa. 110:1] ‘The Lord [i.e., God] said to my [i.e., David’s] Lord [i.e., Jesus], sit at my right side until I put your enemies [in full subjection] beneath your feet.’
[It was] David himself [who] said by [inspiration of] the Holy Spirit [Psa. 110:1], ‘The Lord [i.e., God] said to my [i.e., David’s] Lord [i.e., Jesus], sit at my right side until I make your enemies the footrest [i.e., in subjection] under your feet.’
But which one of the angels did God ever say [this] about [Psa. 110:1], “You should sit at my right side until I put your enemies [in full subjection] beneath your feet?”
