Isaiah 60:7

Isaiah saw other nations, ancient enemies of Israel, bring offerings typical of their way of life. Evidently there will be a literal temple and altar in Zion then (cf. Ezekiel 40-43). The sacrifices offered there will be for thanksgiving to God. God will glorify the millennial temple as the focal point of worship at this time. Isaiah’s vision of the future Jerusalem included a temple and altar (cf. Isaiah 60:13), but John’s vision of the future Jerusalem excluded both (Revelation 21:22). The solution is probably that Isaiah described the millennial city, and John the eternal city.
