Isaiah 19

At the same time that Isaiah speaks of the burdens of Egypt, he prophesizes  that -

"In that day shall there be a highway out of Egypt to Assyria, and the Assyrian shall come into Egypt, and the Egyptian into Assyria, and the Egyptians shall serve with the Assyrians.
24 In that day shall Israel be the third with Egypt and with Assyria, even a blessing in the midst of the land:
25 Whom the Lord of hosts shall bless, saying, Blessed be Egypt my people, and Assyria the work of my hands, and Israel mine inheritance."  (Isaiah 19:23–25)

Even to the point that -

"In that day shall there be an altar to the Lord in the midst of the land of Egypt, and a pillar at the border thereof to the Lord."  (Isaiah 19:19)

Could an "alter" suggest a temple in that day?
