Zeal for God’s House and Reproach for Faithfulness
The speaker bears reproach because of devotion to God, is alienated even from family, and says, “the zeal of thine house hath eaten me up.” The same verse also speaks of reproaches directed at God falling on the sufferer.
The New Testament uses both halves Christologically. John 2:17 says the disciples remembered the zeal line in connection with Jesus cleansing the temple. Romans 15:3 quotes the reproach line explicitly of Christ as the supreme example of not pleasing himself. These are inspired New Testament applications and belong in the highest-confidence Christological layer.
