New Defender's Study Bible Notes
46:4 a river. The river out of Eden, dividing into four streams (Genesis 2:10-14), was a type of the great river flowing from the millennial temple (Ezekiel 47:1-12), and the even greater “pure river of water of life,...proceeding out of the throne of God and of the Lamb” (Revelation 22:1, 2) in the holy city New Jerusalem.
46:4 the city of God. The city of God is not the church, but “the holy city, new Jerusalem” (Revelation 21:2), where will be the eternal dwelling place of God in the midst of His people. The city is not heaven, for it is “coming down from God out of heaven,” and will be established forever on the renewed earth. “The new heavens and the new earth, which I will make, shall remain before me, saith the LORD” (Isaiah 66:22).
