Matthew Poole and continuators on Revelation 19:8

8 And to her was granted, that she should be arrayed in fine linnen, clean and white : For the fine linnen is the righteousness of the saints .

That is, to the Lamb's Wife, whether Jews or Gentiles, or both.

That she should be cloathed with the Righteousness of Christ, reckoned to her for Righteousness.

This is the Righteousness of the Saints, called the Righteousness of God, Rom. 1.17. a Righteousness through the Faith of Christ, Phil. 3. 9. called Righteousness in the Greek, because there are many Saints to be cloathed with it; and because it is imputed both for Justification and Sanctification, not to excuse us from Holiness, but to make up our Defects.

Marginal references: Psal. 45.13, 14. Ezek. 16.10.; Or, bright.
