John 2:17

It was written ... - This is recorded in Psalms 69:9. Its meaning is, that he was affected with great zeal or concern for the pure worship of God.

The zeal of thine house - “Zeal” is intense ardor in reference to any object. The “zeal of thine house” means extraordinary concern for the temple of God; intense solicitude that the worship there should be pure, and such as God would approve.

Hath eaten me up - Hath absorbed me, or engaged my entire attention and affection; hath surpassed all other feelings, so that it may be said to be the one great absorbing affection and desire of the mind. Here is an example set for ministers and for all Christians. In Jesus this was the great commanding sentiment of his life. In us it should be also. In this manifestation of zeal he began and ended his ministry. In this we should begin and end our lives. We learn, also, that ministers of religion should aim to purify the church of God. Wicked men, conscience-smitten, will tremble when they see proper zeal in the ministers of Jesus Christ; and there is no combination of wicked men, and no form of depravity, that can stand before the faithful, zealous, pure preaching of the gospel. The preaching of every minister should be such that wicked men will feel that they must either become Christians or leave the house of God, or spend their lives there in the consciousness of guilt and the fear of hell.
