Mark 12:36

36 For David himself said by the Holy Ghost, The LORD said to my Lord, Sit thou on my right hand, till I make thine enemies thy footstool.

Ver. 36. Said by the Holy Ghost ] The Psalms then are a part of Holy Writ by Christ’s own testimony, who also, Luke 24:44 , divideth the Old Testament into the law of Moses, the prophets, and the Psalms. Yea, Psalmorum liber quaecunque utilia sunt ex omnibus confinet, saith Augustine after Basil; the Psalms are a treasury of all holy truths.
