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,…”

“Zeal - That fervent love which I have for thy house and service, and glory, and people. Eaten - Exhausted my spirits. Upon me - I have been as deeply affected with thy reproaches, as with mine own. This tho' truly belonging to David, yet was also directed by the spirit of God in him, to represent the disposition and condition of Christ, in whom it was more fully accomplished, to whom therefore it is applied in the New Testament, the first part of it, Joh 2:17, and the latter, Rom 15:3. Psalms 69:10”

“69:9 Though the psalmist concerns himself with God and all that is holy, insults have been his earthly reward. This verse was later applied to Jesus’ anger at the Temple’s money changers (John 2:17) and to his undeserved suffering (Rom 15:3).”

“zeal: Psa 119:139; Kg1 19:10; Ch1 15:27-29, Ch1 29:3; Mar 11:15-17; Joh 2:14-17 and the: Psa 89:50, Psa 89:51; Rom 15:3 Psalms 69:10”
