Charles H. Spurgeon on Psalms 119:139

My zeal hath consumed me. "Zeal" is a high degree of love; and when the object of that love is ill treated, it vents itself in a mixture of grief and indignation, which are sufficient to wear and "consume" the heart. This will be the case where men rightly conceive of that dishonour which is continually done to God by creatures whom he hath made and redeemed. But never could the verse be uttered, with such fulness of truth and propriety, by any one, as by the Son of God, who had such a sense of his Father's glory, and of man's sin, as no person else ever had. And, accordingly, when his zeal had exerted itself in purging the temple, St. John tells us, "his disciples remembered that it was written, The zeal thine house hath eaten me up." The place where it is so written Psalms 69:9, and the passage is exactly parallel to this before us. Horne.
