And it shall come to pass in the last days, that the mountain of the Lord's house shall be established on the top of all the mountains, and shall be exalted above the hills; and all the nations shall flow unto it. And many people shall go and say, Come, and let us go up to the mountain of the Lord, to the house of the God of Ya'aqov; and he will teach us of his ways, and we shall walk in his paths: for out of Ziyyon shall go forth Torah, and the word of the Lord from Yerushalayim."
Isaiah (2:3) and Micha (4:3)
The almost identical vision of the prophets sees Jerusalem and the future Temple as a facility for instruction and bringing forth God's word. The Temple is described as a place to receive blessings for all humankind. Moreover, Isaiah emphasizes that all peoples will be welcome to worship at the Temple:
Also the sons of the stranger, that join themselves to the Lord, to serve him, and to love the name of the Lord, to be his servants, every one that keeps the sabbath and does not profane it, and all that hold fast to my covenant. Even them will I bring to my holy mountain, and make them joyful in my house of prayer, their burnt offerings and sacrifices shall be accepted on my altar, for my house shall be called a house of prayer for all peoples."
Isaiah 56 7-8
Arise, shine; for your light has come, and the glory of the Lord has risen upon you ... " See Isaiah chapter 60 for a description of the future glory of Jerusalem.
