Psalms 69:9

For the zeal of thine house hath eaten me up - My zeal - my ardor - in the cause of religion (that is, of thy pure worship) has been so great as to consume me. It has been like a devouring fire within me. Zeal is represented under the idea of heat - as it is in the Greek language; and the characteristics of heat or fire are here applied to it. This passage is quoted in John 2:17, and applied to the Saviour, not as having had originally a reference to him, but as language which would accurately describe his character. See the notes at that passage.

And the reproaches of them that reproached thee are fallen upon me - This, too, is applied, in the same way, to the Saviour, by the Apostle Paul, in Romans 15:3. See the notes at that passage.
