For howsoever one may in some cases pray sitting, yet it is most probable that David would in this Holy place, and upon this occasion, use a more Humble and Reverent gesture, such as kneeling is, which therefore David prescribeth or adviseth, Psal. 95. 6. and Solomon accordingly practiseth, 1 King. 8. 54. 2 Chron. 6. 13. How infinitely unworthy am I and my Family of this great honour and happiness!
