In Rev. 17 and 18 Babylon has two aspects: the religious aspect, signifying the Roman Catholic Church, and the material, physical aspect, signifying the city of Rome, the capital of Antichrist’s kingdom (see note Rev. 18:2^1a). God’s people need to come out of Babylon in its two aspects (Rev. 18:4).

Isaiah was sent by God with God the Spirit. In the New Testament the Father sent the Lord Jesus with the Spirit of God (Luke 3:22).

Referring to the prophet Isaiah.

Referring to Cyrus in Isa. 44:28 and Isa. 45:1, typifying Christ as the Servant of Jehovah. God loves Israel, loves His kingdom, signified by the city of Jerusalem, and loves His house, signified by the temple. In subduing Babylon and releasing the captives of Israel, and in charging Israel and supporting them to build up the temple and the city of their God (Ezra 1), Cyrus did God’s pleasure. Thus, God loved Cyrus. It was a matter of love for God to use a Gentile king to do what was in His heart.
