Ibn Ezra, on Isa 2:2

“And in the last days the mountain of the house of the Lord shall be prepared on the top of mountains, and it shall be exalted above the hills, and all nations shall flow unto it.”

“This will take place, as the prophet says, In the last of the days. That is, in the days of Messiah, which are the last of the days of the world. Those days have not yet come; for since the days of Isaiah there has never been a period free from war. We learn from Josephus, and the literature of the Persians and Medes, that during the whole time of the second temple in Jerusalem war had never ceased. Moreover,.’ the prophet distinctly declares, Neither shall they learn war any more. And shall be exalted. We know that the mount of the temple will not be physically raised; but what the phrase means is, that it will be established in such a way that people will hasten up to it from the four comers of the earth, as if it were higher than all hills. ונהרו And they will flow. Root, נהר ‘to flow’; comp. נהר river, which is so called on account of its flowing motion.”
