The Scofield Bible Commentary, by Cyrus Ingerson Scofield, [1917], at sacred-texts.com
She is not my wife
That Israel is the wife of Jehovah (Hos 2:16-23); now disowned but yet to be restored, is the clear teaching of the passages. This relationship is not to be confounded with that of the Church of Christ.
(See Scofield) - (Joh 3:29).
In the mystery of the Divine tri-unity both are true. The New Testament speaks of the Church as a virgin espoused to one husband (Co2 11:1); (Co2 11:2) which could never be said of an adulterous wife, restored in grace. Israel is, then, to be the restored and forgiven wife of Jehovah, the Church the virgin wife of the Lamb; (Joh 3:29); (Rev 19:6-8). Israel Jehovah's earthly wife (Hos 2:23); the Church the Lamb's heavenly bride, (Rev 19:7).
